The Samsung D900 is a compact sliding phone with a 3.13 megapixel digital camera. It's an impressively slim slider - Samsung say the SGH-D900 is the thinnest slider ever - at just 13mm thick and 85 grams in weight. It forms part of Samsung's "Ultra Edition" range, and the SGH-D900 also has the name Ultra Edition 12.9, the 12.9 referring to the thickness of the handset in millimetres. In addition to the 3.13 megapixel camera, the Samsung D900 has a 2.1" 240x320 pixel TFT display, 80Mb of internal memory with microSD expansion, stereo Bluetooth, quad-band GSM with GPRS and EDGE and also a TV output. The fact that Samsung have managed to squeeze all of that into such a tiny handset is an impressive feat. There's also a multimedia player capable of playing back MP3 and AAC audio formats, a digital power amp and document viewer, and presumably the Samsung D900 has all the usual things that you'd expect from this type of handset
