Sony Ericsson S500i

The S500i measures a pocket-pleasing 1.4cm thick, though at 9.9cm long its reaching candybar-length proportions. The casing is glossy plastic, and has a tactile rubber-feel back panel. The front casing is a bit squeaky when pushing up and down, which points a finger at some cost savings. The spring-action is smooth and substantial enough, however.
