My fingers are "sprawled" across the three alphabetic rows, and I have no particular discipline regarding which finger (or even which hand) hits which key.
I'm curious -- have you ever tried typing using two full keyboards, one for each hand? Your sprawl style seems like it might work well with such a setup. Before I got my kinesis ergo I was typing using two keyboards and I found it quite comfortable since I was able to place them apart from each other so that my arms stay nice and comfortable.
Hm, that sounds very interesting. I imagine it might work and I will try it next time I have a second keyboard handy. It may even make backspacing faster for me (currently I backspace using two fingers rapidly alternating – I find this faster and more accurate than relying on autorepeats – being able to use four fingers should be an improvement).
