I have a new 15 GB iPod and I was wondering what are the must have accesories. I ordered an iSkin exo as I thought that above all, protection was important. Eventually, I would like to get an iTrip and the remote. What I would like to do with my iPod is the basic use, plus use it in a car and use it hooked up to a stereo. Considering what I would like to do with it, what is most suggested to get as I go along over the next few months or so? Thanks ahead!
