I have the 30 Gb and the wife has the Nano I think it is 5 gigs. I like the Ipods as far as function and easy operation. The downside is both of ours are broke the nano will not turn on and the backlight has gone out in mine. Maybe we got some bad products but seems to me for the price they would be more durable if you buy one get it at an electronic store with the extended warranty. Apple wants an obscene amount of money to repair these.
