Using a portable drive is a great idea, and these days they are not too expensive. But there are programs that you can use to load iTunes from your iPod, as well. If you google something like "upload computer from iPod" you will find lots of them. I used one when we switched computers, and it worked well and didn't cost anything for the first 10 or so uses, and I only used it once. Unfortunately, I don't remember what it was called, but, as I said, there are quite a few of them.
