"The Nano 4G feels impossibly light and thin, with a seamless metal construction that prevents it from snapping like a twig. A slightly curved design gives the Nano 4G the essence of an airplane wing," Bell reports.
"The Nano's 2-inch screen size remains unchanged from the previous model, as well as its 1-inch wide scroll wheel control," Bell reports. "Because Apple has flipped the Nano's screen on its side, menus and user interface get a dramatic overhaul from last year's model. Menu text size has increased slightly and album cover art takes up less real estate on the main menu. In a bid to increase the accessibility of the Nano for people with impaired vision, Apple has included a font size setting on the fourth-generation Nano that makes its menus more legible--a nice feature even if you have 20/20 vision."
"If you passed on last year's iPod Nano and are still holding on to a first- or second-generation Nano (or possibly an iPod Mini), there's no better time to bite the bullet and get an upgrade. Given its competitive price, attractive range of colors, and improved user interface, Apple's fourth-generation of the iPod Nano is its best yet," Bell reports.
