I'm glad valve when for the market that VR will be able to standout in the most (freedom of monument around a room). I just hope they have a system that will tell you if you are about to crash into walls (and that it will actually release this holiday and not in the holiday of 3015).
I think they should try it with just one touch pad (the right one) as the one on the left seems to be redundant as there is an analog stick that would be good enough for movement and could aid the right most touch pad for cursor input. I think putting just a d-pad there would make more sense...
