I think it's pretty generous of the writer to consider 70-90 wpm an expert typist. I've never spent any actual effort of learning any techniques and I can easily get 120 wpm on almost any basic keyboard and up to 140 wpm on my main keyboard at home (which happens to be a regular gaming keyboard by logitech). Blank key caps seems more like a gimmick than actually helpful and personally I couldn't drop the arrows either. I know Vim bindings are all fun if you IDE supports them, but you can't really navigate around the OS comfortably if you have to hit Fn + your faux arrows every time you want to move the focus around.
