I got sick of looking at all the debris (don't ask!) that had settled into the keyboard of my G5 iMac. I pulled the keys to wipe it down and in the meantime used the keyboard from my old G4 Powermac. Wow! What a difference! The key action is so much smoother -- it makes typing a breeze. I'm now using it as my main keyboard. Anybody else notice this or is it just me?
