Apple’s 2010 music event brought a number of welcome updates to most of the models in the iPod lineup. The shuffle has regained the buttons that were removed in the 3rd generation models, the nano became much smaller and gained a clip much like the shuffle has, and the nano also became an iOS device complete with a multitouch screen.

Apple updates iPod Nano
Though it is constantly overshadowed by its larger, iOS brothers, the iPod Nano still has a dedicated following due to it’s extremely small size.
Though the design of the device hasn’t changed much if at all, the interface is now supposed to be easier to navigate.
Apple has also added sensors built into the device for running and jogging, this essentially makes the device more usable out of the box, removing the need for users to buy a separate Nike sensor.
The multi-touch Nano has become something of a fashion item, with multiple companies now producing watch wrist bands specifically for the device, and Apple has now added new watch faces to the Nano for exactly that purpose.
The new model is available today in 7 different colors, 8GB/$129, 16GB/$149. Read more
