Review: Pantech Matrix Pro
I can only imagine that the Matrix Pro is going to appeal to a certain set of users. Those who very specifically want a non-touch version of Windows Mobile with access to a QWERTY keyboard and numeric dialpad for calling, the Matrix Pro is for you.
Even if the form factor is what you're looking for, there are some things worth considering. The Matrix Pro is a large phone. The media playback capabilities are limited at best. The included browser is nearing extinction (though alternatives exist), and there's very little users can do to customize the limited menu system.
On the plus side, calls sounded good, battery life was decent, and the camera takes pretty good pictures.
Depending on which features are most important to you, then the Matrix Pro could be worth considering.
