Two unlocked Android devices.  Two part video.  Two manufacturers.  Dogfight time!  Aaron brings the LG Optimus 4X HD and GSM Samsung Galaxy Nexus together for a head to head comparison.  The Optimus 4X HD was announced at Mobile World Congress earlier in the year and packs a 1.5 GHz quad-core NVIDIA Tegra 3 CPU, 4.7-inch IPS HD (720p) display, 8-megapixel camera with 1080p HD recording, a 2,150 mAh battery, and Android 4.0 with LG's custom UI.  Samsung's Galaxy Nexus is powered by a 1.2 GHz dual-core TI OMAP CPU and offers a 4.65-inch Super AMOLED HD display with PenTile, 5-megapixel camera with 1080p recording, a 1,750 mAh battery, and Android 4.1 Jelly Bean.

They're both spec'd well, though the Optimus 4X HD brings quad-core computing to the table.  That said, the Galaxy Nexus is only $349, while the Optimus comes in at just under $600.  Which one is the best all-around deal?  Part 1 of 2.
