Since I have a Nexus 7, there's absolutely no need for the Surface RT (especially if I add a Wedge ).
The Pro is very tempting as the next laptop (I'm mainly a desktop user though) - but I'd prefer to see a better battery life, more RAM (4GB max. wtf?) and an option to bundle either cover for a much lower price point. It's an essentialy accessory, +US$50 for the touch and +US$60 for the type, when bundled, sounds reasonable.
However... just tempting. There's a few interesting Ultrabooks in that price range as well.
