Having written 1200 words on it, my observations are mostly that it would probably be good to learn to use the right-hand shift key as well as the left-hand one (typically I use the left-hand shift key and hit the space bar with my right thumb exclusively), because (most especially because) the " key is above the 2, which is standard on European keyboards but which is weirder than hell to me. Anyway, my left wrist is pinchy from trying to finagle the already-too-small (to my mind) left-hand shift key and the bizarrely placed quote key, so I'm gonna have to learn to hit shift with my right pinky. It's very soft-touch, so I expect that wouldn't trigger the ulnar nerve problem. I hope. We'll see. :)
The entire thing would also probably be made easier if I were typing on a table instead of on my lap, but overall, I'd say it works pretty well. I type faster than the keys are currently set to respond to (gotta fix that), so I prdiclygt sntences thtlook likeths, but overall, pretty good.
I have just exactly enough head cold to be very, very runny-nosed without actually feeling particularly bad. I can't decide if this is a good or a bad thing.
