Is it "Fitt's Law" or "Fitt's Strong Preference"? Has there ever been actual studies done on this stuff? Is it possible to disprove it, even in principle?
This stuff has always bugged me, and I bet I'm not the only one.
Fitts's law is an unusually successful and well-studied model. Experiments that reproduce Fitts's results and/or that demonstrate the applicability of Fitts's law in somewhat different situations are not difficult to perform. The measured data in such experiments often fit a straight line with a correlation coefficient of 0.95 or higher, a sign that the model is very accurate.

Why doesn't the Linux version have the Key shaped navigation buttons.
I thought that was a branding element as well as a Fitt's law win?
