What would you do?

I think you should keep the Nano and use it over your Shuffle! Even better if it's the new one (with video capability). I don't know if you can sell your Shuffle (don't know how much you'd get back for it) but keeping the Nano is a better idea since it has more memory than Shuffle. But of course, it depends on how much music you listen to/ store in these devices and also if you really need the cash. In that case, you don't need your Nano and can sell it off :).

I would keep it as a backup. If there is too much music on your Shuffle you can use the Nano. I have no idea what holds more, I cannot even afford to buy them, and I probably could not afford to get the music from Apple. I would have to put my own cds on them. How did you win it by the way? Was it in one of those join so many and you will win an Ipod Nano? I was wondering at the cost of joining, comparing it to the cost you would normally pay, etc.

personally, if i were you, i would keep it as a backup. there's really no point in selling it off, ended up your old player broke down and you have to cough up money to buy a new replacement in the end. it's really not worth the money, time and 'precious music time'...
