Frankly, I'm a little baffled when anyone states that there are significant differences between OSX, Windows, and Linux when it comes to everyday use. Except for minor differences in the number of mouse clicks and specific icons that minimize, maximize, and close each window all operate very similarly.
There's not much difference. I can move between all them (and Amiga OS olr NG derivatives) w/o any problem.
I also can't see any clear advantages (although OSX and Amiga OS do boot quicker).
