Medfield is a new generation of Atom, and it's a quantum leap forward in performance and efficiency. RT may not be everything that the x86 version is, but it's definitely going to be usable. People complaining about not having access to their old shit are being pretty narrow minded, especially when you consider that you still have to pay for apps for an android or i-device.
It's also baffling as to why news sites think that just because Microsoft is releasing their own tablet, that other companies aren't going to bother. I mean, google has its own tablet, and yet plenty of others make android tablets. The licensing for Win8 isn't even all that expensive, it's something like 35 bucks for RT, and IIRC it's less for x86 because the full copy doesn't include Office software or WMP.
