Can the Atrix 4G Really Become Your Next PC?

GMGruman writes "The Motorola Atrix 4G got a lot of attention at CES because of its ability to dock to a monitor, keyboard, and mouse and run the full desktop Firefox browser in addition to its Android apps. Now that it is shipping, I took the Atrix 4G and its Multimedia Dock and related peripherals out this week for a test-drive to see if delivers on this 'post-PC' promise. The verdict: It's a good first half-step toward mobile devices being your primary computer. The end of the Windows hegemony is in sight."
