I have a Ipod Touch 1st generation. I'm pretty happy with it. I mainly use it for music and games. But as it is a 1st generation, it's condition isn't great and I think it's time to upgrade. But now that the new Psp Go has come out I'm temped to get that instead because it can play music and the games seem alot more involved (that's a good thing). Should I buy a psp go instead of a new ipod touch?
