in my opinion, 80gb is better....i mean ur music/vids library will only grow right? my 30gb is full now, have to constantly select the things i want to put in...such a hassle...

and the price is cheaper now, so it's quite a good catch...about the battery, the 30gb battery isn't bad...mine needs a recharge after 3-4 days with approx. 3-4 hours use daily (music + a couple short vids).. the only real advantage if u watch vids occasionally, i guess the 80gb longer battery will suit you more...
