I was offered a straight up trade for a 16GB iPod Touch. I don't know what to do. 16GB is enough space for me, but I'm afraid I won't like the touch screen or that it's more fragile then the Classic. It would be cool to have all the features and apps the Touch has though. What makes the 1st gen different from the current model? I can just upgrade to the latest firmware to have all the current features right?
