Microsoft gave a preview of Windows 8 at its BUILD event in Anaheim, CA today. In a radical shift from previous versions of Windows, Windows 8 is built with a special emphasis on a touch interface using a tablet as the primary device, although the OS runs on regular desktop and notebook computers also.
This is still an early preview release and there are still no doubt numerous kinks to work out, most notably visible at 5:25 of the video below. Microsoft gave out Samsung tablets with Windows 8 pre-loaded to about 5,000 BUILD attendees. Some are reporting fan noise and excessive heat coming from the Samsung tablets, but this may just be because of extra debugging/development code running in this pre-beta version of Windows 8.
After watching some hands-on demo videos, my impression is that the interface is not as intuitive as it could be, and may be frustrating for some users (namely pulling in the "charms" interface on the right side of the tablet). Nevertheless, I applaud Microsoft for striving to innovate, and I look forward to seeing the final product. If you were one of the BUILD attendees who got a Samsung Windows 8 tablet, please share your experiences in the comments below.
