Bill Gates today unveiled a new PC prototype designed to "enhance today's computing experience and usher in the next wave of innovation for the PC industry" during his opening keynote at the 12th annual Windows® Hardware Engineering Conference (WinHEC).

Co-developed with HP and code-named "Athens," the advanced PC prototype represents an evolution of the PC as a center for communication and collaboration, one that simultaneously simplifies PC operations while merging all forms of communication -- including next-generation voice, video and text messaging -- into a consistent, streamlined design.
