The Surface Pro 2 hits two of the biggest weak points of the original design: battery life and heat/noise. The battery life is underwhelming relative to say the MBA 11" (which has a smaller battery), but the Surface Pro 2 takes that from unusably bad to just bad.
That said, I don't think it's "good enough." It's not a cheap machine: 8GB/256GB model reviewed by Gabe retails for $1,299. It's got a small screen and a keyboard/touchpad combo that, on an Ultrabook, would be considered absolute trash. I think you have to really love that Wacom pen to justify the Surface Pro 2, and that makes it a pretty niche product. Of course, "niche" can be turned into "market-creating" but with continued mis-steps like underwhelming battery life, it's not clear Microsoft can make the "pen tablet PC" market happen.
