Aaron reviews the Motorola Atrix 4G, the first phone with a dual-core NVIDIA Tegra 2 processor. In addition to the snappy CPU, it has a 4-inch qHD display, 5-megapixel camera, front-facing camera for those MySpace shots, and Android 2.2 with MOTOBLUR (which will frustrate some potential buyers). On paper, the specs are awesome, but the phone lagged at various points throughout testing. Is it the best Android phone on AT&T, or is the HTC Inspire 4G the phone to get? We'll figure it out. Part 2 of 2.
