The I-pod touch has a touch screen.
There is none. iPod Touch 3G IS third generation.
The i-touch has a touch screen, the i-nano does not.
Storage capacity is the only difference.

difference between high tech positioning and high touch positioning?
Not much. The only big difference is that the 3rd generation has a better processor, so runs around 50% faster. Also, the 3rd generation iPod Touch is available in a 64GB version, and is also cheaper.
They are the same phone.
The 3rd generation of iPod Touches just has a faster processor, and everything is done just a little bit faster.
the main difference are the cameras
The third generation introduces new hardware that is found in the iPhone 3GS. (increased RAM, better CPU & GPU.) The third generation also includes the voice control support from the 3GS which apple calls "VoiceOver".
There are certain games that you cant get on the ipod 1st generation also you you cant update ipod 1st gen with the new softwares but with the 3rd gen you can carry on updating it.
