it may be depending on what you add
8gb is very reasonable, i was worried about the same concept when i got my touch so i got a 64 gb lol. way to much space. i still have 50 gigs and i hav everything i want. but to hav extra space for new stuff, i wouldnt go with pictures. other than that try to keep it down to about 3 movies, 1000songs and around a page of apps. because when you get the ipod it only has 6.8 gigs cuz apple downloads the menu and that takes away from the 8. if you do this you will be fine and hav extra space fo rwhen new stuff comes out.
