The #1 reason Surface RT will fail

The 16x10 dimensions do not conform to the golden ratio like the iPad. It's unusable in portrait mode. Essentially Ballmer said to make it perfect for widescreen video and screw everything else. There are literally tons of educational apps and games that run in portrait mode on the iPad that will never ever be ported to Windows RT because of this. I think once again Microsoft got sucked into a fad(video) without considering the bigger picture.
