The Surface RT is an ARM based tablet with Windows RT, the Surface Pro is an Intel based processor with Windows 8 Pro on it... but there are Atom based tablets and they generally run Windows 8 PRO, actually. To be honest, I think all of the Atom based tablets are defacto NON-RT tablets, as RT *is* the Windows for ARM variant. Make sense?
It is ALL very confusing. That is a big part of the problem for Microsoft right now.
But yeah, for me, it was all a question of how much detail I wanted to go into explaining the various configurations of Windows 8 and hardware platforms. It would have been a whole article in itself and honestly, that has been done all over the place already.
