neo keyboard layout for life!
If you use a keyboard regularly you should consider learning an alternative layout, since the qwerty layout was designed to slow the typist down in order to prevent jamming on typewriters.
You have to move your hands a lot which may cause medical problems later on.
I moved on to neo when my wrists started cracking whenver I moved 'em. Now they are just fine.
neo, colemak and dvorak are decent ones.
