We could debate all day about whether the original Surface Pro was supposed to be more of a tablet, or a laptop with a detachable keyboard. Either way, we think we can agree on this: The original wasn't perfect in either role, not with its short battery life, heavy build and kickstand that wasn't designed to be used in the lap. Now, less than a year after the original came out, we have the Surface Pro 2, which addresses many of the shortcomings we complained about on the original. In particular, it moves to a two-stage kickstand that sits less precariously on people's legs. A Haswell CPU, meanwhile, should take care of the battery life problem. Even the keyboard covers have received mild upgrades, though unfortunately, they're still not included in the $899 starting price. But does all of that add up to a real improvement?%Gallery-slideshow101465%
