The Nano 7G has a bigger screen, and is more iPod Touch like.
FYI, the 6G had a "revision" last year, but it wasn't a completely new product. The 6G is a brand new product.
Some hints of "iOS" in here. Multi-touch remains, but there is an addition of a "Home" button.
We can see here the home menu, music player, radio, pictures, fitness, and video apps.
Bluetooth was something many people wanted with the 6G and it usually required an adapter, the 7G has it built in.
Video was absent in the 6G, the 7G has video playback!
There are many colors to choose from.
The 7G is 5.4 mm thick, and is thinner. There is no "back clip".
The new screen is 2.5 inches diagonally.
16GB Nano 7G for $149, launch date in October 2012
The new "EarPods" earphones.
The iPod "Product Red" line.
