The first big news is that this version does indeed fix 3.0�s flaw that caused images to render improperly in the Gallery app. I�ve noted this flaw numerous times--in part because it feels like such an obvious blemish on an otherwise solid start to the Honeycomb/Android 3.x platform. While Google hasn�t gone into too much detail as to what caused the issue to begin with, I do have confirmation from Google that 3.1 should fix this issue. I can hazard a few guesses, but ultimately, what matters is that it�s fixed�which is why I look forward to trying out 3.1 on an array of tablets and seeing how my photos look.

Other additions to 3.1 include support for the Open Accessory and USB host APIs. By building the USB stack into Honeycomb, the platform now gets USB host abilities and tablets running Honeycomb now have operating system level-support for managing USB peripherals--including gamepads, joysticks, and storage devices--directly. Technical terms aside, this means that Android 3.1-based tablets will be able to power other gadgets through USB.
