I'm in the market for an iPod but I'm not sure which one to buy. Was hoping the experienced could help me with my decision. All I need in the 10GB really. But I'm wondering if it's worthwhile purchasing the 20GB for the dock and remote. What's the advantage of the dock (other than obviously giving the iPod a nice place to sit while charging and synching)? Does anyone have the remote but not find it useful? Just don't want to spend the extra cash if I don't need to. Wanna save that for the next generation of iPods. Thanks!
