I think all these people who go buy a new mouse and suddenly own are placeboing themselves.
		
		
	 
Agreed, but what about those people with relatively decent skills, that suddenly find themselves doing much worse, with a new/different mouse?
Controls DO make a difference, both in terms of technical specs, and in terms of more subjective human-factors compatibility issues. (Such as size/shape/weight.)
Those factors tend to suggest that the "placebo factor" is probably smaller than the real issues. I know when I switched from my old roller-ball two-button mouse to a fancy 5-button optical one, that I later discovered had half the DPI of my mechanical one, my FPH went way down in UT. So now I use my 5-button for web browsing, and my good old 2-button PS/2 for "serious gaming". 
(Yeah, I should probably try out one of those MX510s some day. But my current $1 mouse serves me pretty well for gaming right now.)
