I currently own both a Ipod Shuffle (2nd gen) and a used but excellent condition 2GB Nano (2nd gen as well). I've found that I'm having difficulty squeezing all of my music (around 1.3 gb) on to the nano along with my podcasts. Besides about 1MB of photos, their is nothing else on the nano. Is their any way to compress the files or change the format so I can still listen to them but have them occupy less space. If not, does it make sense to try to snag a 4-8GB 3rd Gen Nano on ebay? I've seen refurbs and NIB models with 60 day Apple warranties for very low prices and was wondering if it made more sense just to get one? Thanks!
