I'm not trying to tell you what you should like for typing, since there's nothing worse than a backseat typer, but maybe you should give the pro keyboard a chance first?
I have the smaller Apple USB keyboard, and at first I didn't like it at all, because of its light touch and lack of "spring" in the keys. But after a few months, I found that I was typing faster than ever on it, and I dreaded going back to the older-style keyboards.
Well this is just my experience...but if you decide to ditch the pro keyboard and need a buyer, I'm interested. Please drop me an email if you want to sell your pro keyboard, (or make a donation to a poor graduate student

), and maybe we can work something out.
