I thought Windows 8.1 was the defecto standard.
Never have I seen a more apt typo - funny thing is, I saw a commercial last night for one of those PC repair/registry/whatever apps that practically shouted about how "Microsoft is using fear to make you buy Windows 8" (as opposed to your beloved XP box, natch.)
It all ties back to why Intel is now (should say, now more than ever) casting about, looking for new markets for their chips... PCs ain't selling, server lifecycles are getting longer (VMWare pretty much helped stretch that out), and there's not much outside of those two which would encourage PC sales.
(I wonder if Intel will ever stop navel-gazing at tablets and fire up their now-dead Digital Home Group again; they had a fairly decent idea with the chip-in-a-TV thing. Fun group of guys to work with as well...)
