1st and 2nd GenerationsEdit
The first generation was like a much larger, High Definition version of the iPod Touch. It had the basic abilities to game, play music, surf the Internet, etc. The second generation wasn't much different, except it had slightly more processing power.
3rd and 4th GenerationsEdit
The third generation was much better, as it included the A5 Computer Chip, harder material, iOS 6 and Siri. The fourth generation included the even faster A6 chip, and the new Lightning Plug charging cord.
