Earlier today, we got a complete demo and some seat time with the Motorola Atrix 4G for AT&T at Motorola's CES event, including its HD multimedia dock and laptop dock. The phone looks similar to the Samsung Vibrant, but with a black screen bezel and a tastefully patterned matte back cover. Build quality is very good, as we'd expect from a Motorola device. The QHD (960 x 540) display is gorgeous and the phone feels ultra snappy, thanks to the dual-core processor running Froyo. In fact, despite still running preliminary firmware, we recorded a blazing 2,616 score on the Quadrant test. The power button at the top back of the Atrix 4G also serves as a fingerprint reader, and there's a dual-LED flash flanking the 5 megapixel camera. Check out the gallery below and read on for the details -- and the complete demo on video -- after the break.
