On this inaugural day of the Surface Pro I got the 128 Gb version with the Type Cover (blogging on it right now).
I tried to see what kind of serious chops it had and I thought I would try to install Battlefield 3 to test out the processor and graphics power vs my 3 year old machine that drives Battlefield 3 pretty well.
It wouldn't run after the install and gave an error saying that "This game will not run on a virtualized environment". So there isn't anything out there yet as I fear I might be the only one to try this so far on the first day.
I am about 97% through the download and install on Battlefield Bad Company 2 on Origin right now and so should be able to let you know soon if it works with older versions of the game.
