I am a big fan of the kinesis advantage keyboards but I really do wish they had an extra thumb key so you could have cmd, ctrl, and option keys on both sides.
I went from an Advantage 360 to the Glove80 and I like the thumb clusters a lot better on the Glove80. In addition to having more keys, I find I can reach all of them without having to move my hand position as much.
