It's not a Treo

The Palm Centro is the first non-Treo, as well as the smallest and lightest smartphone from the company. It measures 4.2 inches high by 2.1 inches wide by 0.7 inch deep and weighs 4.2 ounces, yet manages to pack in all of the features of a Treo and then some. But perhaps the best feature? Its $99 price tag (with a two-year contract with Sprint).
