Does the Surface run apps outside the Windows Store? I haven't been keeping up but I last browsed Best Buy's Surface section and they wanted not only 2 grand but they were only able to run apps from the Windows Store. That meant no Angry Birds, No Plants vs. Zombies, no Cut the Rope, and a lot of other apps missing, meaning you're about on par with an old BB10 BlackBerry for apps. Great though if all you do is business.
For the price, though, I'd expect far more than a mere tablet. I would expect something more mind-blowing than the most expensive HP Spectre.
AFAIK, there's no *.exe variant of Angry Birds, Cut the Rope, etc either. Meaning you miss out on a lot of popular mobile games that aren't available for Windows. That's what killed Windows phone.
