So doesn't Windows work right now? Not quite so (until next year sometime) according to this Fortune Magazine article. Ironically, Apple have always assumed "It should just work" (their raison d'être I believe) and when it comes to their technology (software or hardware) at the very least they assume "it does work".
I think this marketing message for the next release of Windows is broken, especially for someone whose been using what appears to be a not "just working" operating systems since Windows 2.0 :-(
