Google has just announced its next-gen Chromecast streaming stick, and just like earlier reports said, it's taken on a circular form and has donned more colorful shells. The company says its antenna system allows it to stream higher-resolution videos significantly faster, with less buffering. It even comes with a feature called "Fast Play" that gives it the ability to establish a connection with your TV more quickly than the original version can. Fast Play works by preloading content -- it can, for instance, start downloading a series episode -- the moment you fire up the media player's app. In addition, Mountain View has redesigned the Chromecast app (for both Android and iOS) to list Cast-enabled applications installed on your device, to find content within them and to display its latest offers and updates.
