How boring and predictable. Microsoft needs to use some of their marketing power to come up with brilliant new ways to fuck things up. We've already seen the whole "Windows93, oops, make that Windows95" thing, and we've also recently been witnessing the whole "Damn, accidentally released an alpha console". I predict that Vista will cause at least a minor explosion somewhere.
Of course, this will hopefully be the first edition of Windows that I never have to use, ever.
