Late yesterday Microsoft revealed [3] what it would be calling its upcoming Windows update. There are three versions, starting with Windows 8--the plain vanilla "one size doesn't quite fit all, at all" variety. Then there's Windows 8 Pro with boosted encryption, device managment, connectivity, and whatnot. Lastly, Windows RT, a flavor of Windows 8 for ARM-powered devices like tablets. And, oh, yes, there's a fourth version mentioned as a footnote on MS's post: Windows 8 Enterprise, which'll have extra features that "enable PC management and deployment, advanced security, virtualization, new mobility scenarios," and more. Are you confused? Microsoft has long faced criticism [4] for "spamming" buyers with numerous Windows versions, sometimes for no clear purpose other than lining MS's pockets. This list is smaller than Windows 7 suffered, but it still needs a cross-reference table to explain the different packages' powers.
