Something I really disagree with is suggesting to use Dvorak or Colemak keyboard for typing speed improvements. From my experience with Dvorak, and what I think most research shows, changing doesn't make you any faster. If you have no idea how to touch-type and need to start all over, then maybe it would be ok to start out with a new keyboard just for something fresh, but unless you are trying to prevent RSI, I would argue that Dvorak and other keyboard layouts are pretty useless.
