Not sure OGG was in a finished state at the time of the first iPod? Then again, I can't even remember if the first iPod was AAC + MP3 or just MP3... I know Fairplay was added by a sw upgrade.

Also, saying OGG is free is an interesting tack. From what I've read, it uses plenty of patented techniques - it's just that any player that has an MP3 license has paid the fees to be able to use these patents. If a big volume OGG-only player came along, I can believe the patent holders would try to extract their cut. It's open & free, but to say it doesn't build on any of the work carried out by all the other people working on perceptual audio coders isn't really true.
