The Pantech Matrix Pro, recently released by AT&T, is a unique dual slider phone with both a QWERTY keyboard and a full number keypad.
It has a 2.0 megapixel camera, Bluetooth 2.0, a microSD card slot, and 128 MB of RAM. It comes with a nice protective pouch that also doubles as a polishing cloth, a very small AC adapter, and a headphone adapter dongle.
In some ways it’s the best of both worlds, but there are a quite a few tradeoffs which make it hard for me to recommend this device wholeheartedly.
Design and Build
The Pantech Matrix Pro is a dual slider phone, so it’s somewhat “fat” but still pocketable and comfortable to hold in the hand. It is very solidly built, and when I manipulate the sliders I find that they work smoothly and strongly “snap” into the appropriate position whether they are being opened or closed.
The Samsung Propel offers a sliding keyboard, camera, and 3G antenna in a compact form factor.
The Xperia X1 is the first Windows Mobile smartphone from Sony Ericsson. It’s an ambitious start: a WVGA touchscreen, built-in keyboard, GPS, 3G, and a host of other high-end features.
