"The P990i (Best Current Price: =A3326) is a significant product for
Sony Ericsson. It's a sophisticated Tri-band/3G device that gets you to the
point where you can really start to minimise on the number of devices and paperwork you carry around. In addition, the push e-mail capability especially helps to bring business mobility in a safe, secure and fast environment. Secure, relatively simple and fast access to e-mail and the Internet are critical requirements for true office mobility, so it's a shame the P990i doesn't excel. The ability to access e-mail and calendar while out of the office is critical for mobile executives as they no longer need to return to the office to perform this task, but the P990i's convoluted Symbian 9.1-based menu system and tiny QWERTY keyboard are nigh on impossible to fathom - Windows Mobile 6.0 and BlackBerry really do shine by comparison."
