This will not work, microsoft still don't get that the hardware is almost immaterial to ecosystem, no one needs a keyboard on a tablet, no one needs a trackpad especially on a tablet no one needs usb ports or any of that stuff they seem to have tacked on.
I bet it'll ship with no proper media store or a very poorly stocked one, no books, no podcasts, no proper video store or rentals and poor to non existent syncing and almost certainly poor cloud integration, I bet it won't even work properly with their windows 8 phones. You can guarantee there is no real master at the helm of this bumbling project. Metro is ugly out of date and just plain pants.
I'm not saying that they can't do it right but microsoft isn't structured the right way as a company to function at a level apple does.
They've already made massive mistakes IMHO with design and hardware features before i've even seen the screen.
VS iOS which has remained the same game for some 5 years now?
Clearly you've never seen Metro in action, outdated my @ss.
