Aaron takes a look at Android 4.2 (also called Jelly Bean) on the Samsung Galaxy Nexus.  It's a mostly evolutionary update from Android 4.1, but brings some new features such as gesture typing in the stock Android keyboard, improved lock screen features (namely, easier access to the camera and widgets), and new improvements to the camera.  And who can forget that new camera feature - Photo Sphere!  It's available for download now on unlocked Galaxy Nexus smartphones.
