The Palm Centro made its debut in Fall 2007 as the smallest and lightest Palm OS based smartphone to date. It is the third new model from Palm this year after the Treo 755p and Treo 500v. Palm basically took all that's good about the 755p, and packed it into a much leaner and lighter body. The Centro brings a number of high end smartphone features including 3G wireless data and a full qwerty keyboard into the $99 range.  

The Palm Centro is initially available in a choice of two colors from Sprint, onyx black and ruby red. The casing is a smooth plastic with silver trim accents that wrap around the sides, back and front buttons. The cases colors have a nice subtle sparkle finish to them when viewed up close. Overall the new design is a good refinement of the classic Treo form factor, though the Centro does have a much more plasticy feel to it than previous Palm devices. Palm still can't seem to make it much thinner, but the compactness and pleasantly symmetrical rounded design of the Centro provides a positively smaller impression.
