for those interested in being walked through any sticky situations with itunes or an ipod. Here is the main situation you need to walk VERY carefully through.
You have an existing ipod (or some various device) that has a library of music on it. You've changed computers and added itunes to it. You are now wanting to connect your existing ipod to the new computer.
If this is your situation, shoot me an email and I'll give you a call and walk you through the background of the computer to successfully transfer your songs to the new library instead of the library deleting them off of your existing ipod.
