Hello, I'm a PC, and welcome to the 2009 Worldwide Developers Conference.
I wanted to be the first to wish all of you a great conference filled with incredible innovations that will keep Apple at the forefront of the...
You know what? I think I can do that better.
Let me try that again, please.
I'm sorry.
Take two.
Hello, I'm a PC.
Welcome to the 2009 Worldwide Developers Conference.
I wanted to be the first to wish you all a week with some innovation, but not too much, please.
Yeah, I like that.
Take three.
Okay, hear me out.
You've already sold over a billion iPhone apps.
Don't you think that's enough?
I mean, iPod Touch is a runaway success.
Maybe you could just slow it down, and maybe you could float a few ideas my way, right?
I could use some snazzy apps, some things.
Why?
I hope you're thinking of some great ideas, because I'm thinking of great ideas.
What are your ideas?
So you'd prefer this?
Clip.
I don't even know what to do anymore.
Canceled.
Get out.
Cut.
No.
Take 60.
Hello, I'm a Mac, and what PC is trying to say is have a great conference.
Thank you.
Thank you very much.
Welcome to the 2009 Worldwide Developers Conference.
We have an amazing week planned for you.
It's incredible.
For all of you, and I mean all of you, there's over 5,200 developers from 54 countries around the world.
It's incredible.
And can't you feel the love in this room?
I mean, it's intense.
This is the best, best level of excitement and anticipation for our developer conference yet.
And there's so many good reasons for that.
I'd like to show you just one.
This is incredible.
This is a chart of OS X users in the first five full years of Mac OS X, from 2002 to 2007.
Great steady growth, adoption of Mac OS X.
This is in shipments.
This is actual active users, up to 25 million.
But something incredible has happened over the last two years.
To show you that, I need to change the scale of the graph a bit.
Keynote, magic move.
And this is what's happened.
With iPhone and iPod Touch, we've tripled, tripled the number of active users of OS X across these products.
We've tripled the install base of customers to run all your amazing applications.
It's just astounding.
No wonder everyone's trying to race behind us and follow in our footsteps.
No wonder there's so much excitement around what's happening.
So in this keynote, I'd like to tell you about some of the things we're doing on the Mac and the iPhone and iPod Touch to continue this amazing market growth, to continue to create products that our customers just love to use, to continue to give you technologies so that you can build the world's coolest applications with them.
To help me do that, today I'll be asking Bertrand Serlet, our Senior Vice President of OS X Software, to join me.
And also Scott Forstall, our Senior Vice President of iPhone Software.
Now I get to begin with a section on the Mac.
And I'm really happy to do that because the Mac products are the best they've ever been at Apple.
We make incredible products.
And increasingly, the majority of our customers, when they buy a new Mac, choose one of our notebooks.
We make these amazing new notebooks.
And we're in love with the way they've come out lately with this new design we've come up with.
It actually started a year and a half ago with the MacBook Air, where we created a technology we call the Precision Aluminum Unibody Enclosure.
Unibody for short.
And it lets us create a notebook that's sturdier, made of amazingly beautiful materials, packed with features, and best of all, insanely thin and light.
We like this design so much that we took it across other products.
The 13-inch MacBook, the 15-inch MacBook Pro, the 17-inch MacBook Pro just earlier this year.
And all have done extremely well and customers couldn't be happier with them.
And even though we have a huge lead over anyone else in the notebook business making incredible, gorgeous designs, we don't want to stop.
We want to continue to extend that lead.
So I'm really happy to show you first today a brand new version of the 15-inch MacBook Pro.
Now, it's built on this unibody architecture that allows us to pack more things into a thin design than anyone else does.
So built in is a revolutionary lithium polymer battery.
We started this earlier in the year with the 17-inch MacBook Pro.
This battery gives an amazing up to 7 hours of battery life.
That's 2 hours longer than before, 40% greater battery life.
And we do it in a more environmentally friendly way.
The majority of notebook batteries in the market today get about 300 full recharge cycles before they start to have diminished ability to retain a charge.
These new lithium polymer batteries of ours are over 3 times longer, over 1,000 recharge cycles.
So that means a typical notebook user will get about 5 years of life before they see diminished charge in that notebook battery.
That's incredible because that's longer than a typical notebook life.
So most customers may never need to change the battery in their notebook because it will last that long.
And when they do, we have a great recycling program in our stores if they want to take advantage of it.
Unlike our competitors who in that same time, often the customers will go through 3 batteries, not dispose of them properly, and it's just not good in the environment.
So you get this incredible battery life, this long life battery, all in a design that's just as thin, just as light.
And that's amazing to deliver.
When you open it up, the new 15-inch MacBook Pro has a gorgeous display.
In fact, it's the nicest display we've ever put in a notebook.
It has 60% greater color gamut, which means more vivid colors on the display.
It's still insanely thin.
And as you go around the I.O. side, you see there's all the I.O. on the left-hand side.
If you zoom in, you see something different this time.
In place of the ExpressCard slot, which was used by less than a single digit percentage of our customers, there's a new SD card slot.
But why an SD card slot?
Well, most all our MacBook Pro customers have digital cameras today.
Incredible digital cameras like this Canon DSLR.
And of course, you can plug it in with a USB cable, but customers really like the convenience of popping out the SD, and they all standardize on SD now because of the speed and capacity they hold.
And now they have the convenience of just popping it right into the MacBook Pro and importing your photos right into iPhoto, Aperture, and Photoshop wherever you are.
So you have a built-in SD card slot, but there's a lot more to this new 15-inch MacBook Pro.
It is the fastest notebook we've ever made.
You can configure it with up to a 3.06 GHz Intel dual-core processor with 6 MB of L2 cache.
That's the fastest processor we've ever put in a notebook.
You can also expand it with more memory, up to 8 GB of 1066 DDR3.
You can get up to 500 GB, half a terabyte inside this notebook, up to 7200 RPM.
Or, if the way you like to go is SSD, you can get up to 256 GB on that.
So this is an incredible new 15-inch MacBook Pro.
It has all these features and capabilities, and it starts at an even lower price of just $1,699.
Now, that's $300 less expensive than before, and I know a lot of customers are going to appreciate that.
You can configure many different thousands of configurations on our online store, but here are three standard channel configurations that you'll find.
At $1,699, it starts with a 2.53 GHz Core 2 Duo, 4 GB of DDR3 memory, a 250 GB hard drive, the NVIDIA integrated 9400M graphics, and all those features like the built-in battery and the SD card slot.
At $1,999, you get a faster processor, 2.66 GHz, a bigger hard drive, 320 GB, and now you get both the integrated and the discrete NVIDIA 9600M GT, so you can choose even faster graphics or longer battery life.
And the highest-end channel configuration, $2,299, that's $200 less expensive than before.
It's now 2.8 GHz, 500 GB hard drive.
It's an incredible configuration.
So those are the new configurations of the 15-inch MacBook Pro.
Now, of course, that joins the 17-inch, which also has that amazing built-in battery, and today we're updating the configuration of that as well.
It's also 2.8 GHz.
It's also a 500 GB hard drive.
It retains an ExpressCard slot because there are some specific solutions that customers have, for example, some high-end audio products.
And that's now $300 less expensive than before, $2,499.
And all of these, the new 15-inch MacBook Pros and the updated configuration of the 17, are shipping today.
So the MacBook Pro is an amazing notebook computer.
We make another unibody computer as well, a 13-inch aluminum design.
And today we're going to update that too.
The new 13-inch notebook has the same revolutionary built-in battery, and this is incredible.
In a notebook this small and this thin and light, it also gets up to 7 hours of battery life.
Again, 2 hours more than before, 40% more battery life.
And yet it stays just as thin and just as light.
And also this 13-inch notebook gets that same incredible new high-vivid color, 6% greater gamut display.
And if you look on the I.O. on the side of it, there's that SD card slot as well.
Now this did not have an ExpressCard slot, so we really challenged the engineering team to make room to fit in that SD card slot, and they did it.
Now you're looking at this and you're saying, wow, it's got a lot of the cool features of the 15-inch MacBook Pro.
At what point isn't this just a MacBook Pro?
So we challenged the engineering team, let's go further.
What other things can we add to just make it a MacBook Pro?
So this new 13-inch notebook also can expand up to 8 GB of memory.
This new little 13-inch notebook can also have up to 500 GB of storage, a 256 GB SSD inside.
And then a feature that I know many of our customers love about a MacBook Pro is the built-in LED backlit keyboard.
It's now standard in it as well.
So a lot of great features.
Let's go back to that I.O.
If you look a little further down past that SD slot, you're going to see something else we've put in there as well.
Because doesn't every MacBook Pro deserve FireWire 800?
So with all of those features, just like the 15-inch, just like the 17-inch, it deserves the name MacBook Pro.
Now in every way, this is what you expect from a MacBook Pro, except one.
It starts at just $1,199.
Now that's less expensive than the 13-inch aluminum MacBook it replaces.
And that's amazing.
So here's the standard channel configurations.
Again, you can build even more in the store.
At $1,199, you get a 2.26 GHz Core 2 Duo, 2 GB of DDR3 memory, the integrated NVIDIA 9400M graphics, a 160 GB hard drive, and all those great features like the long-life battery and the SD card slot.
At $1,499, 2.53 GHz, 4 GB of memory, 250 GB hard drive.
So great configurations.
And the new 13-inch MacBook Pro is available today.
So that's the 13-inch.
That really completes the MacBook Pro family.
13, 15, and 17-inch.
New features, all amazing battery life, all backlit keyboards, the ability to expand.
And they start at just $1,199, $1,699, and $2,499.
Phenomenal pricing.
It's the most affordable lineup we've ever had.
Now if you know some of the other things we've been up to lately, you know that just a week and a half ago, we updated the configuration of the white plastic 13-inch MacBook.
So that has a slightly faster processor and bigger hard drive.
So to complete the picture, we're also going to update the MacBook Air today as well with some more aggressive configurations and pricing.
Now a 1.8 GHz, it's a faster processor for just $1,499.
That's $300 less expensive than before.
And if you like SSD, you can get a 128 GB SSD config with a 2.13 GHz processor.
That's $1,799.
And if you looked where we were just before this keynote started, that's $700 less expensive than the previous configuration.
So these notebooks, and they already were so far ahead of the competition in so many ways, and they just leap even further ahead now.
And one of the areas they're far ahead, and we're really proud of this, is being environmentally friendly as well.
All of these notebooks, and no one else can say this, every MacBook, every MacBook Pro, every MacBook Air meets the stringent EPEAT Gold standard.
That's really important for environmentally friendly design.
And every one of them meets Energy Star version 5.
That's the new version coming out this summer, and they already all meet that.
And because of that, we're really proud to say this is the world's greenest lineup of notebooks.
So great notebooks.
Thank you.
Amazing hardware.
Products that our customers really are going to love and appreciate.
And what does it deserve?
Great hardware deserves great software.
I think this audience knows that better than anyone.
Great software.
So to tell you what's going on with Mac OS X, I'd like to invite up Bertrand Serlet.
Thanks, Phil.
Good morning.
Over the years, the feature set of Mac OS X has grown to an incredible portfolio.
And our latest release, Leopard, is the most successful software product Apple has ever had, with features like CoverFlow in Finder, Quick Look, Time Machine.
Our users really love it, and so does the press.
It's by far the best operating system written for the vast majority of consumers.
What a sharp contrast with what's been happening up north.
Here's the press again.
Vista has failed to catch on with mainstream computer users, while businesses have shunned it outright.
Indeed, Microsoft has dug quite a big hole for themselves with Vista.
And they're trying to get out of it with Windows 7.
But underlying Windows 7, you have the same old technologies: DLLs, the registry, disk defragmentation.
No end user should ever have to know about that.
The user account control.
That's the security subsystem that prevents your PC from being infested at the cost of tons of alerts.
And in Windows 7, to address the alerts problem, even more complexity front upon the user.
So that's Windows 7.
Same old technology as Vista.
Fundamentally, it's just another version of Vista.
We come at it from such a different place.
We love Leopard.
We're really happy how it has turned out.
We're proud of Leopard.
And so when it became time to think about the next big cat, we decided to name it Snow Leopard to build upon Leopard.
And the challenge that we set for ourselves is to build a better Leopard.
So what does that mean?
Three things.
First, lots of refinements across the board.
Second, powerful new technologies.
And third, Exchange support.
So let me talk to each in turn.
First, refinements.
You know, Mac OS X is made of a lot of projects, over a thousand projects.
And for Snow Leopard, we've decided to refine over 90% of all those projects.
So let me give you some examples.
The Finder.
We actually love the way the Finder is in Snow Leopard.
And so for Snow Leopard, we did not change it, at least the user interface.
What we did do is rewrite it using our modern toolbox, Cocoa, so that we are better positioned for the future.
And from that rewrite, there's lots of little benefits, lots of little touches that you'll start noticing once you start using Snow Leopard.
Next, the dock.
In Leopard, we added a beautiful 3D rendering for the dock.
But I don't know about you, but my desktop sometimes has a little more clutter.
And we've had a feature for the longest time on how to deal with clutter.
It's called Exposé.
So what we did is we've built Exposé into the dock.
So the way it works is you just click and hold on an app tile, et voilà, you select the window you want.
Next, installation.
That's probably your first contact with Snow Leopard.
And we've made it even faster, up to 45% faster.
But maybe more importantly, after you install Snow Leopard, you actually recover some disk space.
Over half the footprint of the OS, over 6GB more space, thanks to technologies like file system compression.
Preview is, of course, our favorite way to view images and PDF files.
And we've made common operations faster.
There's also lots of little touches.
The one I like is about text selection in PDF files.
In Leopard, you can actually select text and copy-paste it into other applications.
But it doesn't always follow the logical order of the text.
In Snow Leopard, we've used a little bit of AI to actually infer the structure of the document.
Next, Chinese input methods.
It can be cumbersome to enter a character, a Chinese character, with a keyboard.
But you've got a trackpad.
Why not use it?
This is exactly what we did with Snow Leopard.
You can draw with your finger, and the computer picks the most appropriate character, even predicts the next character to come.
Next, Mail.
Everyone uses Mail.
We've made it even faster.
And quite a bit faster for common operations, as you can see.
Next, Safari.
We've been working on a new version of Safari called Safari 4, with features like top sites.
It's been in beta for a couple of months, and I'm very proud to announce that today, we are shipping Safari 4 for Leopard, Tiger, and Windows.
Safari 4 offers unsurpassed speed.
Speed for HTML and speed for JavaScript for your web 2.0 web pages.
This chart here shows the standard SunSpider JavaScript benchmark, and the scale is multiples of IE8 speed.
It's also very, very standard.
In fact, the gold standard for the ultimate test for standardness is the Acid 3 test, and it passes 100%.
To put that in perspective, IE8 passes 21%.
So Safari 4, of course, will also be available on Snow Leopard.
It will be included in Snow Leopard.
And in Snow Leopard, there's a couple extra features you don't get on the other platforms.
The first is crash resistance.
Let's say you browse the web, have quite a bit of state buildup.
Well, let me tell you a little secret.
The number one cause of crashes across all of Mac OS X is actually browser plugins.
So if your plugin crashes in Snow Leopard, you just get this rectangle, but the rest of your windows are intact.
All you need to do is reload that page, and that's it.
You haven't missed a beat in your browsing.
The second feature that you get only on Snow Leopard is even more speed.
You know the JavaScript benchmark I showed you a few slides ago?
That's a 32-bit benchmark.
When you run in 64-bit, you go even faster.
And of course, we run applications in 64-bit.
QuickTime.
We have an all-new QuickTime in Snow Leopard.
We call it QuickTime 10.
It's an all-modern stack.
It fully leverages hardware acceleration.
It's super efficient.
It's color correct.
And we're debuting a new technology for streaming called HTTP streaming because it's all based on standards: HTTP, AAC, H.264.
It works with any web server, like an Apache server.
It's really cool.
So since we had such a change in the backend of QuickTime, we decided to also change the user interface of the QuickTime player.
And this is what it looks like.
As you can see, the content is center stage.
In fact, as you start playing, the on-screen controls, including the window title, go away to let you enjoy your contents.
So what I'd like to do now is have you see some of the features and little touches that we've added in Snow Leopard.
And for that, I'd like to ask my colleague, Craig Federighi, VP of Mac OS Engineering, to demo to us some of the refinements.
All right.
You guys are too kind.
All right.
So I'm going to cover three areas in this sneak peek of Snow Leopard, and we're going to start with Dock and the Finder.
Now, one feature of the Dock is Stacks.
Stacks makes it really easy to get quickly at your documents and your downloads without cluttering your desktop.
And in Snow Leopard, Stacks handle large contents better than ever.
I can now scroll through a large stack, and if I have subfolders, like this vacation folder, I can just drill right in without leaving Stacks.
Yeah, pretty nice.
Now, I could open this document right here, but I want to jump into the Finder to show you a couple nice touches there.
So here we are in icon view.
Looks pretty familiar, but if you look in the lower right, you'll see that we have a magnification control.
I can now magnify my thumbnails, and this is a live preview, so I can actually step through this page PDF right on its icon.
I can even play a movie right in its thumbnail, and I can magnify, of course, while it's playing.
Really, really cool.
Oh, yeah.
But, you know, my favorite new feature in the Dock is Dock Exposé.
And to demonstrate, I want to recreate a little bit what my desktop can tend to look like after a long day.
Lots of Mail compose windows, lots of Safari windows, lots of images open in Preview, and so forth.
Now, fortunately, the Mac has long had a fabulous solution for this problem in the area of Exposé.
So I can activate Exposé and step back and see all my windows across all my open applications.
But, you know, I usually know what application has the window I'm looking for, and now with Dock Exposé, getting at it couldn't be more natural.
So let's say I want to get at a window inside of Preview.
I just click and hold, and there are my Preview windows.
I want to see in Safari, click and hold, and I'm there.
Mail, same thing.
And, you know, I have, it looks like I have an unread email message I'd like to take a look at.
I don't even have to open it.
I'll just zoom in and take a quick look.
I can zoom in right in Exposé without switching apps, and when I want to finally bring a window to the foreground, I click and it slides right in.
But, you know, Dock Exposé also makes it easier than ever to move content across windows, even if some of the windows aren't visible.
So let's say I want to go back to that Finder window and get a video to drop inside this email message.
I can just Dock Exposé into the Finder, find the image I'm looking for, drag it over to Mail.
Mail springs into Exposé.
I select the window I'm looking for and drop it right in.
Yeah, this really smooths out some of your Mac workflows.
Very nice.
Okay, the next big area I want to cover is Safari 4.
Snow Leopard ships with the final version of Safari 4.
And if you're a Safari user, and I hope you are, like me, it is the fastest browser on any platform.
You know, if we want to visit an image-rich site like ESPN, we hit it, boom, stunning speed.
And that speed extends to JavaScript sites as well.
Let's go to Google Maps.
Loads quickly, and whether it is zooming, panning, switching modes, just stunning, stunning speed with that Nitro JavaScript engine.
But, you know, Safari also makes it faster and easier than ever to track my top sites, the sites that I visit most.
I click on the top sites icon here, and I get an intelligently laid out, beautiful panoramic view of all the sites I visit most.
Getting to one of them couldn't be more natural.
I want to go visit ESPN.
I click, it fades in, and I'm viewing.
I want to go back, it fades right back out.
And top sites is even tracking for me when a site that I view has changes since I've last been there with this little blue star.
The final really great area of Safari I'd like to cover is full history search.
So if I want to go back and find a site that I visited recently, I just click in this search history filter in the lower right, and I get a cover flow view across my browsing history.
Right, very easy to find what I'm looking for.
But not just that, I have full spotlight search of this content.
And not just of the URLs or of the window titles, but of the text in the pages.
So I type Maui, not K Maui, let's type Maui, and I get all the pages that I've been using, visiting to plan my Maui vacation.
Find the one I want, click, and I'm browsing.
Very easy way to get through my history.
Now the final area I want to cover is QuickTime 10.
QuickTime 10 has been re-engineered on top of modern Snow Leopard foundations, and the QuickTime player has been rebuilt from the ground up to put your video center stage.
Let's take a look now at a family vacation video.
We see the playback controls are elegantly overlaid on the video itself.
And as I start playing, if I move my mouse out of the window, watch how they fade away.
Even the window title bar fades away to put my video center stage.
And when I want to go back to access those controls, they fade right back in.
But another great feature of the QuickTime player now is the ability to trim and share my video.
So I can go here and select trim.
I get a visual timeline of my video.
I can scrub smoothly to find the clip I'm looking for.
Maybe this harrowing cliff jump.
Let's go, whoop, back up.
Find the end point, scrub in this way.
And when I've found what I want, I just click trim, and there's my edited clip.
And then when I want to share it, my sharing options are just a click away.
I can share to YouTube, MobileMe, or iTunes where I could export to playback on my iPhone.
Really, really nice sharing in QuickTime.
Thank you.
So those are just a few of the many, many touches to Snow Leopard.
And I'll be back shortly.
Thank you.
Thanks, Craig.
So, lots of refinements in Snow Leopard.
But there's also powerful new technologies.
And those technologies fundamentally are to take advantage of the power of silicon and bring that to the user experience.
Because when you look at a modern Macintosh, you have an incredible set of components, things that were unthinkable a few years ago.
You have RAM, gigabytes of RAM.
I mean, a few years ago, it was expressed in megabytes.
You have a powerful processor that runs at a frequency expressed in gigahertz, that's multi-core, 64-bit capable.
And then you have a GPU with enormous raw processing power.
But to take advantage of all this, you need the right software.
So we have a number of technologies.
I want to mention three.
First, 64-bit.
Of course, the primary reason to use 64-bit is to take advantage of lots of memory.
Because if your application runs in 32-bit mode, it has an inherent limit with the addressing space at 4 gigabytes.
When you run in 64-bit, it's 16 billion gigabytes.
That's the limit of your addressing space.
In practice, it's unlimited.
Another reason, of course, to run 64-bit is that the processor can do math faster.
So certain things like FFTs will run twice as fast in 64-bit mode.
So for all those reasons, we've been on a trajectory over the last few releases to enable more and more 64-bit.
And Snow Leopard is the final stage where we are running all the major system applications in 64-bit mode.
So, that's 64-bit.
Now let's talk about multi-core, because Moore's law has changed its form.
You know, a few years ago, we were used to always increasing kind of frequency for the chips.
And as the processors hit around 3 GHz or something like that, the expression of Moore's law became there's more and more cores.
And this is a trend that we see continuing in the future.
But the challenge with multi-cores is how to take advantage of them, how to program them.
And the standard answer is threads, multi-threaded programming.
But it's really, really hard.
And it's also fairly inefficient because you never have quite the right granularity.
So we have a solution for this, a new methodology that we call Grand Central Dispatch.
It's built-in support for multi-core across all of Snow Leopard.
It's very, very comprehensive, all the way from a language extension, low-level libraries that are super efficient, high-level libraries to make it really easy to program, integration with all the system APIs, and tools to tune your program.
So just to give you a taste of what it feels to use GCD, let's look at threads in Leopard for, say, the mail application.
When mail is busy, it has a certain number of threads.
And when it's idle, it actually keeps pretty much all those threads.
In Snow Leopard, when mail is busy, it actually uses more threads to take advantage of the multi-cores.
But when mail is idle in Snow Leopard, all those threads go away, giving back resources to the system.
And when you reapply that pattern for every major application, you get a big win in performance and responsiveness.
So that's GCD for multi-core.
Next, let's talk graphics.
You know, the amount of power that you have in cards nowadays is incredible.
We are talking of over one teraflop in raw power.
That's one trillion operations per second.
It would have taken a whole room a few years ago to have that kind of raw power.
And the standard way to use that power is to use OpenGL.
That's what's used for games and graphics.
But we want to move beyond that.
We want to use this power for all kinds of things.
And for that, we've devised a technology that we call OpenCL.
The C stands for computing.
It protects you as developers from exactly what card the user has.
It's based on C, so there's very low learning curve.
It uses sophisticated compilation techniques to optimize.
And it has numerical accuracy, which means you can use that for scientific computation.
We've also decided to make it an open standard.
And many companies are participating.
In fact, all the top manufacturers of graphics chip are in.
So that's OpenCL.
So just three of the technologies we have in Snow Leopard, they are really important because they give us a lot of power in the platform.
And this power is power for us to innovate in the OS.
And it's power for you, for your applications, to gain a competitive edge.
So the next area I wanted to cover is fitting in businesses.
You know, many people nowadays have a Mac at home that they want to take to work.
And it works great because we have Microsoft Office.
That's, of course, the de facto standard.
We integrate really well with IT services.
We have Unix.
And we can run Windows applications via Bootcamp, Parallels, or VMware.
What's missing is Exchange.
So we've decided to build Exchange support into Snow Leopard, into the main three communication applications: Mail, iCal, Address Book.
It's really, really simple to set up thanks to AutoDiscovery in the Exchange server.
You just fill in your email address and your password, and that's it.
You are set up in all three apps.
So what I'd like now is to ask Craig to come back and demo us Exchange.
