As a Surface Pro owner [1], I like:
* Surface 2 loses the low-density screen. I enjoy that low-density has been deprecated.
* The names are right. Surface 2 and Surface Pro 2. No "Surface with Windows RT 8.1" nonsense.
* Haswell, yes please. Longer battery life may assuage some popular criticism.
* Backlit type cover. I hope this is compatible with my Surface Pro.
* Two-position kick stand. I will be envious of this.
* Surface 2 is smaller than Surface RT.
* More memory in the Pro 2.
* Docking station. Depending on the price of that and whether it's compatible with my Surface Pro, I may pick one up. However, I'd prefer to have an inductive charging plate as I have with my Nokia phone. I love the idea of just dropping wireless devices on a plate with no cables, no alignment, no fuss.
I am disappointed by:
* I personally would have preferred a Surface 2 Pro that leveraged Haswell to reduce the form factor to roughly the same as the original Surface RT. But I've never actually drained my Pro's battery, so I'd take lighter-weight versus increased battery lifespan. I'm usually near an AC outlet when I am out and about.
* I would have liked a purely x86 lineup. Bay Trail Atom (or Haswell i3) on the low-end, Haswell i5 on the high-end.
* Windows RT needs help. Remove its artificial limitations.
Overall, I am fairly satisfied. I may want to replace my wife's netbook with a 2 Pro.
