I have a question about my iPod. I have all the music on my iPod and I have now backed up all my music onto my PC which has about 160 GB of space compared to my laptop with 40 GB. Now, if I delete this music from iTunes, I think it will erase it from my iPod the next time I hook up the iPod to my Powerbook. Am I right in thinking this? The iPod is on automatic update right now. Is there some trick to doing this so that it does not delete the music from the iPod? It took almost 100 hours to transfer all my music over to my desktop over airport and my local network so I really would rather not do that again to get the music back on my laptop. Any advice or am I crazy in thinking this?
