Review: Motorola Atrix a powerful smart phone

As smart phones get an increasing array of features, they need faster processors.

The Motorola Atrix 4G, billed as "the world's most powerful smart phone," arrives with 2 gigahertz of processing power - the kind you're more likely to find on a laptop than a phone.

That's notable because there's an optional laptop dock, which makes the phone function as, well, a laptop.
