Bill Gates and Steve Ballmer got on stage at D6 with Walt and Kara to talk... Microsoft, of course. While the company is still being rather coy about Windows 7 -- some have blamed loose lips early on in Vista development for saddling the OS with too high of expectations and making things difficult for developers -- they were nice enough to show off what Ballmer called "the smallest snippet" of Windows 7. The big reveal was multi-touch support, which utilizes technology developed by the Surface team. The taskbar seems to have been reworked a bit, and the demo was running live on a Dell Latitude XT tablet. Apparently Microsoft is reworking the whole user interface with a multitouch experience in mind. Steve reiterated the "three years after Vista" mantra for availability. Not exactly earth-shattering, but we'll take what we can get at this point.

Update: Video added after the break. Enjoy! [Thanks, Dan Z.]
