I feel like the timing of the pro is way off too. Maybe 6 months...or even 3 months ago it would have been perfect. With haswell right around the corner, you are talking about 3x the battery life of the pro and all laptops being this tablet combo
Even the clovertrail CPU is quite hearty, although I see the reason MS went with ivy bridge in the pro (although I'm still baffled with the strategy of RT). Haswell won't be out until next holiday season actually in tablets ready for sale, maybe not even then.
