When Steve Jobs returned to Apple, he made it really clear that Apple's job wasn't to beat Microsoft. Apple then delivered on that assessment and created entirely new markets for themselves. Sadly, somehow, Microsoft went all XOR on our asses. I'm still baffled about how Microsoft is still trying to out-Apple Apple when they've repeatedly proven it's a disastrous strategy (see: Zune).

If Joe and Jane Public buy those, that's great too. Oh, and they will because they'll feel comfortable with Windows, especially if they are told "Oh btw, you can have Windows on your phone and tablet as well as Office now, why bother with whatever Android is or that Apple stuff."
Its also a little silly to expect MS to not try to compete in these areas. Their Win8/Tablet strategy is big and risky and may or may not pay off, but conceding that realm to Apple and Google seems foolish. Personally, I like the idea of a "super tablet" that replaces my laptop entirely as opposed to this odd device that kinda sorta fits between my phone and my laptop.
