I'm writing from the Apple store in Philadelphia, where I've finally gotten to see a G5. They're larger than the G4's, taller and deeper as well, I think, but very beautiful. The finish is what I would call a pearl white. They also seem very quiet, as best as I can tell in a mall store. Let me add to this - it IS quiet; I just listened to it against a G4 in the store and there's a big difference! This is most encouraging for me, as I really care about the noise my computer makes. Only one G5 here (the 1.6 ghz model, and it's pretty fast! I also lucked out and picked up a refurbished iMic for $20US. Cheers, everyone.
