If this link is to be believed, then colemak/capewell/arensito are the layouts that make the fingers move the least amount of distance over the keyboard.
It looks like Colemak is the best supported one of the three, and the most similar to QWERTY.
Does anyone here have experience with the former two layouts, I'd love to know how you went in switching, and what kind of a speed increase you saw?
Would it be worth switching to one of the former two, for an increase in typing speed?
