I was gonna get a 16GB Nano, but my collection will exceed 16GB in not too long. Some of my stuff isn't that important, but I don't want to delete it. I was wondering if there was some easy way to have it automatically sync most of my stuff, but designate only stuff that I don't want synced. Hopefully I could also have it load a selection of the other stuff. So, basically I want to have it sync all my important stuff, and have a shuffle of the unimportant stuff. Can that be done without much hassle?
