There was plenty about yesterday's Android event that didn't make headlines but was worth noting. Hardware acceleration of both 2D and 3D UI elements -- shown off to great effect by Google's Hugo Barra, who managed to scroll through three lists simultaneously without inducing any lag on the Motorola Xoom -- should make Honeycomb as delicious to look at as it sounds, while our personal favorite, the new tablet-specific email interface, should be part of Gmail yesterday. The email UI is built out of elements Google calls fragments, which will supposedly be easy to transition down to smartphones, so thumbs up all around. The video above also runs you through the big news of the day, namely that Android Market can now be accessed via a dedicated website and apps downloaded to your device remotely, along with the equally important (for devs) addition of in-app purchases. Finally, Cee-Lo Green pops in for a video chat session from wherever he is on the internets, and we're all treated to an exhibition of lag-afflicted, awkward conversation. What's not to love?
