Just as the marketing hype around Windows 7 heads toward its peak, a few details are starting to surface about its likely successor.
You may groan but work on Windows 8, as Microsoft CEO Steve Ballmer has referred to it, is already underway.

The next generation of Windows is unlikely to appear for a few years - probably by 2012 - but Microsoft is working on what comes next, even before Windows 7 hits the shelves.
Ballmer for one has implied there is still more to come. "In a sense there's still a lot of work to do [with the operating system]," he said recently in London.
The company remains tight-lipped about the work being done but Ballmer has suggested that improved management and voice recognition are development priorities. There is also speculation that it may feature a 128-bit architecture.
