As a side note, I think it's funny how attached people can get to one keyboard or another. I'm slowly getting used to this MacBook keyboard, though I've been a die-hard lover of the PowerBook/MacBook Pro's tight and low-travel keys since I've owned one for the last 4 years. Ultimately though, I dislike most keyboards because I used to own an ergonomic - y'know the funny looking split ones? - and that was absolutely killer for both teaching myself better typing habits and making sure I don't get carpal tunnel. The only ergonomic keyboards I can find in stores (since you gotta get your hands on those to really get a feel for 'em) these days are Microsoft's and, while I love their Intellimouse Explorers, their ergonomic keyboards' construction just doesn't feel up to par, and there's far too much needless travel in their keys.
But I digress (a lot) - if you're using a non-Apple keyboard on a Mac, enjoy this script for easily swapping the keyboard layout for your Mac computing pleasure.
