O2 Xda Atom Exec

Menu navigation is handled using either the stylus (or, if you're lazy, a finger) or the hardware buttons that lie just below the 2.7-inch 240x320 touch screen. These buttons include a five-way directional thumb pad, accept/reject calling buttons, a shortcut button for the start menu and a button for quick-launching your SMS/e-mail/MMS inbox.
In our Spb Benchmark battery test, which runs the device through constant general usage tasks with the backlight always enabled, the Exec lasted for six hours and twenty minutes. This is a pleasing score; the HP iPAQ rw6828 scored seven hours and three minutes, but this is expected due to its slower 416MHz processor.
The Exec runs on the familiar Windows Mobile 5.0 operating system, upgraded with the Messaging and Security Feature Pack. Among various security improvements, this provides push e-mail capabilities which, provided you've enabled a data service through your carrier, sends new e-mail messages directly to the device without forcing you to continuously login. This is identical to the service provided by the HP iPAQ rw6828 and similar to the BlackBerry's push e-mail system.
