Motorola Q - Top Selling Smartphones

Though the Q may look like a Palm Treo, it is anything but. Much skinnier than that phone, the Q runs on Windows Mobile 5.0, features a full QWERTY keyboard, an EV-DO connection, integrated Bluetooth and 1.3 megapixel camera. It also has video and audio playback, and supports a wide range of multimedia formats, including WMV, MPEG, MP3 and AAC formats.
