Like the iPod shuffle the nano uses flash memory instead of a hard drive. But unlike the shuffle it has a screen and sophisticated controls. The nano comes in 1 GB (US$149), 2 GB (US$199) and 4 GB (US$249) versions. Color choices are black and white.
The iPod nano has a 65,536 color display that can display photos. It connects to a computer via USB 2.0. The headphone jack is at the bottom. It has a standard 30-pin dock connector for hooking up to third-party peripherals. The nano is the first dock connector iPod that can't sync to any PC (Windows or Mac) via FireWire cable, though it can still be charged via a Firewire connection.
New featuresThe iPod nano has several features that appeared later in the fifth generation iPod. These include world clocks, a stopwatch, and a screenlock option. The world clock lets you set the time for cities around the world, and set alarms for each time zone. The screenlock option lets you set a 4 digit passcode; once the screenlock is activated the only buttons that can be pressed are the skip forwards and backwards and the play/pause buttons. The click wheel is used to input the digits to the passcode. If you forget your passcode, the iPod can be plugged into the your computer and be unlocked.
Sound qualityiPod nano uses the same audio codec (the WM8975) as the 4G iPod so that it's sound quality is comparable.
ProblemsThere have been a number of complaints about the nano's screen being too soft, so that it's easily scratched or even cracked if put under too much pressure. The iPod body itself is delicate and can scratch easily. The surface is a soft plastic and normal use can easily damage the surface. For this reason, Apple started to package both the nano and the fifth-generation iPods with soft fabric cloth carrying case which should help prevent scratches to the screen and body. Unfortunately the case doesn't allow access to the screen and controls can only be accessed with difficulty.
