I just got the ipod touch 2nd gen as a present. I don't know if I should upgrade to the newest. I dont use a camera that much, and the retna display is nice, but not completely necassary. Is it worth the upgrade? UPDATE: I before I got the 2nd gen, I had the first gen. I planned to upgrade to the 4th generation, and then I recieved the 2nd gen as a gift.
