Windows 8 reimagines Windows -- it's for the next billion people, he says.
Sinofsky talks about how this team "boldly reimagined" Windows. And there's no doubt this version of Windows looks very different than any version of Windows most consumers are familiar with.
We've had 16 million on installations of pre-release build of Windows 8, he says.
"Windows 8 is computing for the next billion people," Sinofsky says. Similar to Mozilla's argument for Firefox OS, which they claim will get the "next 2.5 billion people" on the Internet.
We've done 650 pages of blogs on Windows 8, he says.
Windows 8 is probably the most-tested beta ever, except for maybe Gmail.
Sinofsky is a prolific blogger. It's one of his traits well-known at Microsoft.
Starting at 12:01 a.m. local time, the new era of computing begins, he says.
Announces ability to upgrade to Windows 8 online and in store.
Announcing a grand opening of Windows Store for apps.
Also announcing a new experience of Windows RT (devices running on ARM processors like tablets).
Of course, these have all been talked about for a while.
Sinofsky talks about improvements that come from Windows 8: better battery life, faster boot time, smaller memory footprint, strong work with partners, and compatibility with Windows 7 hardware and software.
Windows 8 has had 1.24 billion hours of testing, he says. So it better work without bugs!
Upgrades start at $39.99 for consumers, he says.
Among the recitation of facts, I'm looking for a strong argument for Windows RT from Sinofsky, That may come in the follow-up event, though.
Windows really is Microsoft's moonshot. It's so complex to pull off. Critics might say it's too complex. But getting all of the different piece of Microsoft and the computer ecosystem is a monumental task.
Now talking about the user interface and interaction of Windows 8. We're at the start of a new era, he says.
Windows 8 is designed to work with mouse and keyboard, as well as touch. That's the big selling point of the new OS: its flexibility.
Calls the interface "fast and fluid," he says. It's personal and accessible and scalable, he says.
Notes keyboard shortcuts work the same.
I think Sinofsky is dead-on about touch. The very first thing I did when Google gave me the Cr-48 Chromebook demo was touch the screen, inadvertently. People want touch.
All Windows 8 software comes with a simple how-to for first-time users, he says.
Microsoft's big bet with Windows 8 in PCs is touch. It's unclear how much consumers will want or use touch screens. It's going to require some new learning.
Over 1,000 new PCs have been certified for Windows 8, he says.
However, the quality of the manufacturers' touch screens can be hit or miss.
You will see fully capable PCs for Windows 8 for under $300. That's cheaper than some tablets!
He talks of Ultrabooks with touch screens too. Those probably won't be under $300.
That $300 price point for new PCs could be a big motivator to get consumers buying devices.
For anyone having video issues -- refresh now for Flash version (Silverlight stream was broken).
For the home and office, Windows 8 will power a wave of all-in-one PCs.
"These are the best PCs ever made," Sinofsky says.
Sinofsky pitching the touch screen as being integrated alongside keyboard and mouse. It's not a replacement.
Windows has maintained the broadest and deepest library of apps, he says.
With Windows 8, Microsoft is enabling a new wave of apps that are touch enabled.
He says the new Windows Store represents a great new opportunity for developers.
The form factors are really going to matter. There were plenty of new Windows 8 PCs in the lounge area when we came in that, honestly, did nothing for me. There's going to be a lot of experimenting going on with PC makers, and a lot of them are going to produce devices that won't sell.
The Windows Store will be available in 231 markets, according to the slide behind Sinofsky.
