I ordered my first one too last night me = very excited
Well technically it is not my first, but I'm gonna say it is because I was always afraid of the others and I thought I would break them and get in trouble. Plus it has been a while since I did mess about on one.
I have an iBook G4. It's a great machine, and I'm confident you'll love it. As for the iBook issues people keep yapping about, those were the old G3's. Have fun!
