Atrix 4G
The laptop-dock phone that imagined desktop convergence.
The Motorola Atrix 4G is a flagship Motorola smartphone released Mar 2011, with a launch price of $500. It pairs the Nvidia Tegra 2 with a 4.0" qHD PenTile LCD display, a 5 MP, dual-LED flash main camera and a 1930 mAh removable battery. In SpecEagle's editorial review it scores 56/100 — The phone-as-PC dream. Standout strengths: webtop laptop dock — desktop convergence a decade early and early fingerprint sensor on the power button. Main trade-off: pentile display looked grainy.
The phone-as-PC dream.
Motorola Atrix 4G imagined desktop convergence a decade before Samsung DeX — slot it into the Webtop laptop dock and it became a full Firefox desktop. It also had a fingerprint sensor in 2011. Ahead of its time, even if the execution was clunky.
