If you're going to spend a significant portion of each day at a computer, I can't understand why you wouldn't get a keyboard and mouse you are really comfortable with. It is not a 'fetish' (I'm sure there are some people that will fetish over it, rule 34 etc., but not enough that it even deserves mentioning).

I've never ever in my long career heard anyone claim that ' These cherry red's will improve my code by 10%'. To then draw a parallel to bad management metrics seems to me a bit of a stretch.
