I have the new Garageband on my iMac, and I like the fact that you can finally export in mp3! It also seems to just function better as a program in general... But compared to the older '06 version I have on my macbook, there seems to be a major lacking of software instruments in the '08 version. My '06 version simply came with a lot more instruments. Can anyone tell me what's up with that? It's a bit confusing as to why they'd just yank out instruments for no reason... Also if I upgrade my macbook, will I lose the '06 instruments? Thanks.
