The iPod touch has a camera and you can download apps for it. The iPod Nano can not do all those things. The iPod Touch can sometimes do text.
As with most gadgets, it will become a victim of time. This means that the iPod Touch will soon become obsolete, and other things will dominate the iPod Touch. Things will get bigger, or smaller, and better and will do all the iPod Touch can do and more as time goes on.

It is the first iPod touch ever made. It does not have many things the the 2nd and 3rd generations had. Such as a master volume on the outside. Hope it helps
It depends on the iPod model. If it is an iPod Touch, the fine print on the back metal side on the bottom should be 3-4 lines long.
Many things are free on the iPod Touch. Internet access, and over half the apps in the App Store are free.
