That was quick -- Aviate hasn't even finished developing its context-aware Android home screen, and it's already an acquisition target. Yahoo has announced at CES that it's buying Aviate for an undisclosed amount; the web giant wants to use Aviate's simplified, ever-changing interface as a "central part" of its Android software in 2014. While it's not clear just what that entails, the launcher replacement will live on for the foreseeable future -- in fact, the first 25,000 people to use the code "YAHOO" will get into the ongoing private beta.
