I probably won't carry more than 4GB of music. I don't know if the rest of the memory will be enough for me though because I don't know how much is usually stored an the iPod. I'm guessing we don't even really get the full 8GB b/c of pre-loaded software and the IOS. So that would leave about 3.5GB for apps, documents and videos? How large are iPod movies usually? Has there been many cases from you guys here where you regretted buying the 8GB and had to return it for a bigger sized? Just not sure if I want to spend that extra $70.
