I type like 80 wpm on a standard keyboard but that involves lots of crossing over from one side to another. My right hand does a lot more of the work than my left. For some reason I only really type with a couple of fingers on my left hand and all of the fingers on my right so the right usually covers about 3/4 of the keyboard and the left is only doing a little bit of the work. For me then, the split keyboard really doesn't work so well because it's split in a place where keys on the left I generally will be hitting with my right hand instead. Although I guess I could use one of those split dealies if I wanted to train my left hand to pick up more of the work or something.
