This is off-topic, but apparently you never dug Mac OS X keyboard preferences. Mac OS X is much much more keyboard friendly then any Windows ever was (probably with exception of Win 3.x which still tried to follow the aforementioned UI guidelines).
That was actually surprising to myself - when I first started with Mac OS X 10.3
I'm actually a Linux user, though I do remember Windows being pretty annoying when it came to keyboard navigation. I will say that one of the things I love about the mac is spotlight, I wish I could find something like it.
After Googling for 0.5s - http://support.apple.com/kb/HT1343 and also google for "Full Keyboard Access".
Ah, thanks for the information! It hadn't even occurred to me that something like this would be configurable. Is there a reason it's disabled by default? It seems the only people who wouldn't want it enabled would be those who don't use keyboard shortcuts, and it wouldn't impact them in any case.
