Microsoft woos developers with Windows 8 demonstration

took the wraps off 8 and Internet Explorer 10 on Tuesday, revealing a dramatically different Windows for both users and application developers. It validated some of the rumors about the new OS and squashed others.

No target date was offered as to when Windows 8 will be publicly available.

Windows Division President Steven Sinofsky and four Microsoft product managers demonstrated the Windows 8 client operating system at the company's Build conference in Anaheim, Calif.

Here's the upshot of the new features:

The new UI of Windows 8 is the "Metro-style" application which looks much like Windows Phone 7 with ' "Live Tiles" organized in groups and oriented first toward touch. It still supports a keyboard, including keyboard shortcuts, and a mouse, and includes a virtual onscreen keyboard, too. It natively supports a digitizing pen.

Integration with Windows Live will feature prominently and could be the feature that most worries enterprise IT professionals. When a Windows 8 user logs multiple machines into the same Windows Live account, that user can access all machines remotely, even if each of those machines is parked behind a firewall.
