"Although I really liked last year's third-generation fat nano, the iPod nano 4G represents a clear improvement in both form and function. The scroll wheel and subtly tweaked user interface work as quickly and as intuitively as ever. The accelerometer's greatest feat is not the shake trick, but the screen shifting option that allows for a better photo and video viewing experience on what, ultimately, is still a very small player. The added Genius and shake-to-shuffle features aren't exactly groundbreaking, but they do show that the king of digital audio devices isn't asleep at the wheel. It's continual minor tweaks like these to the venerable iPod line that keeps Apple's stronghold on portable media player market intact. Once again, with the nano 4G, Apple has produced the coolest, slickest, and most intuitive sub-$200 flash player you can get, and easily earns our Editors' Choice," Gideon reports."
