Pantech Matrix Dual Sliding Phone Has More Buttons Than SenseFormed from the same genetic ooze as Pantech's Slide Duo smartphone and rebranded Helio Ocean handset, the Matrix is a mildly frustrating device: spec'd with the best, but dressed in the worst. An HSDPA-enabled handset with GPS, a full QWERTY keyboard in addition to a dialpad, and two cameras should have the software to leverage the hardware, but AT&T and Pantech have chosen to stick with an in-house OS rather than opt for Windows Mobile as they did with the Duo QWERTY smartphone. Still, it doesn't look like a bad feature phone for people who message more than they talk, and it's available today at AT&T stores. [Crave]
