Sheri, I have the iPod with video, 30 gb (gigabytes). If you're not interested in video, there's the iPod nano, the largest of which is 4 gb, holding 1,000 songs. My iPod can hold 15,000 songs. I don't recommend the shuffle.

For what it's worth, I think you should go ahead and get the one with video. The cost differential isn't that much ($249 for the 4g iPod vs. $299 for iPod with video 30 gb). Plus, you never know if you might want to download a tv show that you missed. For instance, I missed an episode of Lost which I was able to download and watch while I was in S. Africa.

Battery life is pretty good, although if you watch a video it does tend to run down pretty quickly.

If you order from Apple and you belong to MyPoints you can get points for your purchase. They are still offering free engraving and free shipping too.

Let me know if you have any other questions. My iPod has saved me from many an annoying train ride here in Boston!
