Good luck on your new job.
Well I don't think any of this matters anymore but I've never much cared for the sound of the iPod on MP3 and while AAC is better sounding on it there are other MP3 capable players with better SQ still (look at creative, iRiver, Rio possibly Cowon but I've never heard theirs).

AAC is definitely better than MP3 at lower bitrate but high bitrate MP3s IMO are better still.
