Immerse yourself in the supremacy of the Xda Atom, the world's smallest multimedia PDA-phone. The epitome of power and performance, it is power-packed with cutting edge features such as O2 MediaPlus, Windows Media Player 10, 2.0 Mega Pixel Camera and Microsoft Windows Mobile 5.0. Compact, lightweight and aesthetically pleasing to the eye, the Xda Atom is a true complement to your distinctive sense of style. Weighing a mere 140g, its highly ergonomic form is further accentuated by the brilliance of its 262,000 colours QVGA TFT-LCD touch panel-enabled display. Adding to perfection are the sleek stereo speakers, omni-directional mono microphone and user-friendly navigational buttons.

Big, bold and beautiful

At 128 x 81 x 25 mm and a 285 g, the O2 XDA Exec outmeasures and outweighs even heavyweights such as Nokia's 9500 Communicator, yet remains surprisingly pocket friendly. Borrowing a page from the world of tablet convertibles, the device not only opens to become a clamshell; its screen half also swivels 180 degrees and closes to allow for tablet mode operation, with phone functionality not only preserved in both of these modes but also when closed.

Thumb-a-rific
Opening the Exec is something of a revelation. Granted, the 3.6-inch transflective TFT screen with VGA resolution performs superbly indoors as well as quite good outdoors - yet is trumped by both of Nokia's recent Communicator devices in the latter mentioned scenario. The thumbboard, however, with its comfortably large and bevelled keys, is absolutely superb and - to our astonishment - doesn't take a back seat to that of the highly acclaimed Nokia 9300 Communicator.

Getting the job done
From the perspective of processing power, the XDA Exec can propel just about any application at swift speeds courtesy of its 520 MHz Intel processor. Disappointingly, however, although the device relies solely on non-volatile memory and as such negates the risk of data loss present in past Windows Mobile devices, only 48 MB is available for running programs whereas 44 MB is available for storage. In leighman's terms: expect to make good use of the SD Card slot.
