I wonder myself why they didn't opt for the Atom, but the Surface has probably been on the drawing board for at least 2 years, and a suitable Atom has only just come along to unexpectedly match ARM processors in performance and power consumption. Two things can happen. ARM can take up the gauntlet and try to outdo Intel by producing even faster, better, more power efficient processors (possibly spurred on by companies like Apple). Then Windows RT makes sense. Or Intel and ARM stay more or less neck-to-neck, but as more Windows apps become available, the dichotomy between Windows 8 and Windows RT on tablets becomes meaningless. As my geek relative observed: "What's the point of legacy software compatibility on tablets? Tablets are about moving forward, not backward." Another little observation: hitting CTRL on the simple screen keyboard reveals all the associated shortcut commands on the relevant keys.
