ipod touch

is there much of a difference between the 1st gen ipod touch and the 2nd? Can they all play games?
Answer #1
Yes, they can both play games. The only difference I can think of on the top of my head is that the 2nd Gen can’t be jailbroken yet, apart from that the battery life is longer on 2nd. All I can think of on the spot
Edit: The 2nd Gen also has an in-built speaker, I don’t believe the 1st does
Answer #2
Is this a good bargain?
