I am trying to decide which to get, the 8 or the 16. I have a 30 gb video for music and stuff but im looking at the touch as more of like a PDA. The 8 is cheaper and can do the same amount of stuff as the 16 but it just cant hold as much. This is my dillema save the 100 and probably buy soon or wait for the 16 and might not need that much memory. Any help from people who have been in that situation?
