I want an iPod touch to keep in my car and plugged up to the stereo system. When iOS 5 comes out I could then sync wirelessly when I'm at the house from in the car and not have to take it inside as you all know. My question is should I get the 3rd or 4th generation model. I think the 3rd would be just fine but there is always the what if I.... Question. What do you guys think?
