Samsung Galaxy S III vs. Samsung Galaxy Nexus with Jelly Bean.  It's on.  The Galaxy S III is more of a mainstream device, thanks to the (upcoming) availability on four nationwide carriers.  It offers a 1.5 GHz dual-core Snapdragon S4 CPU, 4.8-inch Super AMOLED HD display with PenTile, 8-megapixel camera with 1080p recording, a front-facing camera, HSPA+ 42 (T-Mobile version), 2,100 mAh battery, and Android 4.0 with TouchWiz.  The GSM Galaxy Nexus in the video rocks a 1.2 GHz dual-core TI OMAP CPU 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.

Jelly Bean offers an incredible speed bump, but the Galaxy S III has some exceptional software features and is more robust in the specs department.  Which Samsung Android is the best?  Part 1 of 2.
