MobileTechReview have published their review of the Pantech Duo 2-way slider Windows Mobile smartphone. 'The Pantech Duo is the same thickness as the juggernaut AT&T Tilt. Simply, there's no way to make a skinny phone when there are two sliders involved. To make the device as thin as possible, the QWERTY keys did suffer: there's very, very little key travel and no doming. This makes for a less than ideal thumb typing experience, though we did like the width of the keyboard overall and the large keys. The keyboard is backlit and easy to read (letters are white and numbers and the Fn key are noted in light blue). Keys are generally where you'd expect them to be with the exception of the spacebar which has moved up from the desktop keyboard and sits in between the V and B keys on the bottom row.
