Microsoft Windows 7

Whether you're updating an old XP box, moving a newer machine away from Vista, or wanting to load up an alternate OS on your Intel Mac, Microsoft Windows 7 ($50-$320; 10/22) is coming soon. Packing features like multi-touch support, new ways to organize open windows and apps, a new device manager, and more, it will also (hopefully) solve some of the compatibility and stability problems that forced Vista off a ledge less than three years after its release.
