O2 XDA II Silver smartphone

XDA II TFT, 240 x 320, 8.89 cm (3.5 ") , Silver The Xda II still boasts its predecessor's sleek, silver design but bestows a much smoother guise due to the external stump antenna being chopped off. Antenna aside, the casing is very similar in size to the original, measuring 70 x 130 x 19 mm. There's no denying the Xda II looks like a PDA. Its specs even outshine some of the best pure PDAs (without phone functionality) available on the market.

Running Microsoft's verbosely-titled Windows Mobile 2003 Software for Pocket PC Phone Edition, the Xda II will be competing with other smartphones such as the Treo 600 (which uses Palm OS), and the Sony Ericsson P900 (Symbian OS-based).

Key features have been considerably bumped up on this latest incarnation of the Xda. Its massive 65,000-colour LCD takes up 74 x 56 mm of the front of the device and appears clear and bright in a range of lighting conditions, thanks to a transflective screen. Housed under its silver exterior is a 400MHz Intel XScale PXA 263 processor with 128MB of RAM, double the amount of memory found in the original Xda.
