The Sanyo SCP-3100 is yet another sign that push-to-talk (PTT) phones are gaining more mainstream appeal. This Sprint clamshell comes in not one, not two, but four different colors--Blue Energy, Always Pink, Espresso, and Pure Silver--which are definitely aimed at a wide audience. The SCP-3100 is also one of very few PTT phones that come with a camera, another sign that it's geared toward more users than just industry professionals.
At first glance, the Sanyo SCP-3100 may remind you of a kid's walkie-talkie, thanks to the plastic exterior and the large speaker grille; the phone looks a bit cheap as a result. Its size and heft (3.31 by 1.83 by 1.01 inches; 3.5 ounces) are good for smaller hands, but the clamshell too bulky to slip in a jeans pocket. Though it isn't a big deal, opening the SCP-3100 takes some effort due to a springy hinge, but the phone cradles your ear comfortably. The SCP-3100 also has an extendable antenna.
