since i learned how to type formally, from school (lame waste of time), it took me several keystrokes.
just don't get one that remaps keys.
the MS natural elite changed the position of the 2x3 insert, home, pgup, etc and the arrows, but the natural pro which i have fixed it =)
also, it depends on your typing style as the first statement impled =)
ultimately, it's only slightly better since to be really good, one would not have to bend one's elbows at all, which is what i am working on, as soon as those cheap keyboards get here.
imagine a keyboard where the qwerty was really split at shoulder length or so apart, with the numeric keypad in the middle. =) that's my plan, they make keyboards with the qwerty split, but cost A LOT!!!.
some say the split is not good for gaming since the keys are mapped, and something funky could happen...
fake, everyone types like an idiot sooner or later ;-) you can just blame the keyboard ;-) which we all do anyway ;-)
