I have had my iPod for a couple years now and I don't think I will ever be able to use up all of the memory! 30G works perfectly for me. It holds songs, pictures, videos, etc. and does tons of other things (I still haven't figured out what half of them are!). Maybe once I start loading up on other things besides music I will begin to use some more of the memory. My only critiques of this product is the battery and the headphones. The battery doesn't seem to last too long. Sometimes it seems like it is dead after 2 hours. The headphones lasted a decent amount of time but the quality in the sound seemed to worsen quickly. Overall I am very happy with the product!
