I just got the regular Apple keyboard (the one with white keys and a clear base) because I really like the feel of the keys. Unfortunately (and I feared this might be the case beforehand), it's one of those keyboards that has a low number of simultaneous keys it can register in a given area. The end result is it won't register pressing "1" if I have "Shift" and "A" depressed. This is a problem in games for me, unfortunately. Good ergonomics foiled by somewhat limited technology.
