Dogfight battle!  The Samsung Galaxy S III is more of a mainstream device, thanks to the (upcoming) availability on four nationwide carriers in the US.  It offers a 1.5 GHz dual-core Snapdragon S4 processor, 4.8-inch Super AMOLED HD display with PenTile, 8-megapixel shooter with 1080p recording, a front-facing camera, HSPA+ 42 (T-Mobile variant), 2,100 mAh battery, and Android 4.0 with the new TouchWiz.  The unlocked Samsung Galaxy Nexus sports a 1.2 GHz dual-core TI OMAP processor along with a 4.65-inch Super AMOLED HD display, 5-megapixel camera with 1080p, a front-facing shooter, 1,750 mAh battery, and Android 4.1 Jelly Bean.
