I'm planning on getting a 15" Powerbook right after the new ones are annoucned, and I have a question about getting my music from my PC to the Mac. I'm pretty sure at the point I have the Powerbook, the PC will be sold and gone, so I'll only have my AACs and MP3s (haven't converted everything to AAC yet) only on my iPod. Can I somehow dump all the music from the iPod onto the Powerbook? or will I have to store the music files as if the iPod is an external HD and then transfer them that way?
