I've abstained from the vote, as I have yet to decide. Sure, the tactile keyboard of the Type Cover 2 sounds promising, but then again, those gestures on the Touch Cover 2 look fantastic (the audience at the Panos Panay event I went to seemed to agree, based on the oohhh's and aaahh's).
When I got to buy my Surface Pro 2 this coming Tuesday, I'll sample writing on both, play around with the Touch Cover 2's gestures, and then make my decision. I'll also consider later purchasing a Power Cover, but I'd also like the Docking Station, and money only stretches out so far.
