It is dominated by a 2.5-inch screen; measures 3×2.2×0.6 inches and weighs 2.1 ounces. The display is touch-sensitive. The body is wrapped in a brushed-metal border, where you can find some tactile controls: a power/hold slider, volume buttons, and a menu key. On the left edge, hidden beneath a flap, are two USB ports: one standard mini for syncing with the computer and one proprietary for use with the included wallwart power adapter. The bottom is home for an SD card expansion slot.

The menu is simple and easy to use. It works with Windows versions back to 98. They also give you a CD that includes a JetShell version which may be very useful.

It has a great deal of interesting features; it offers support for multiple audio codecs, including MP3, Ogg, WAV, FLAC, and WMA–including subscription tracks and it also recognizes prebuilt playlists, and you can also create your own playlist. You can also view photos and videos on the device; it supports WMW and AVI natively.

The sound has a very high quality but the headphones they give you are not very good. If you change them, you will probably enjoy listening to music on the D2. The battery life of 52 hours for audio and 10 hours for video means it doesn’t have any big downsides. Price is $219.99.
