Currently, 4G cell phones are very popular, and the Motorola Atrix offered in the US by AT&T is a 4G phone with plenty of special features. With a 1 GHz Tegra 2 dual-core processor, a 5-megapixel camera, a fingerprint reader, and the availability of a docking station that can turn the phone into a laptop or a desktop computer, the Atrix seemed quite impressive. When we saw Motorola advertise it as the "World's Most Powerful Smartphone," we were anxious to take a look.
