Does anybody have an iPod touch? I'm thinking of getting one for my husband for his birthday/Christmas (he's a December baby). I'm debating whether it is worth it or not. He has an older version iPod right now that he uses pretty much every day at the gym. I'd love nothing more than to just buy him the iPhone but we don't want the added cost on our phone bill right now. Any opinions - pros/cons to the iPod touch?
