Over at Google I/O, the news about Android 4.1 - a.k.a. Jelly Bean, if you haven't heard - just broke.

The first announcement was Project Butter, a new processing framework for Android that should make it run much, much faster - up to 60fps, in fact. The CPU and graphics will now work together in harmony, with the latter being triple-buffered, meaning things like scrolling and transitions should be noticeably faster.
