The latest PDA there is Glofiish X800 is one mutli-functional handset, and I fear for its battery life considering the amount of technology packed in. You get GPS, WiFi, and Bluetooth connectivity in addition to MP3 playback, a VGA camera behind and a 2.0 megapixel camera up in front.A Samsung SC3 2442 500Mhz processor runs the show, aided by 256MB ROM and 64MB RAM. The display could do with a little bit more help though, as it shows only 65k colors on a 640 x 480 resolution. This latest phone called Glofiish X800 measures 113.5mm x 60.5mm x 15.8mm and uses Windows Mobile 6.0 Professional as its operating system of choice. Source
