In a promotional e-mail for the conference, Microsoft said hardware and driver developers could "get the first close look" at Longhorn. In addition to the system requirements, the Redmond, Wash., company said it will detail how to write the drivers needed to connect hardware in Longhorn, along with "future directions for mobile computing and Tablet PCs, Media Center Edition, 64-bit Windows" and embedded versions of Windows.

Most likely our PCs are not quite ready to run Longhorn if you consider the OS is still a couple of years away from actual release (late 2005 - early 2006) and the not so smooth transition to be expected for the completely revamped platform in the new OS, so for now I would worry about other things.
