The new, third-generation Chromecast received a much- needed upgrade. Unlike its glossy color-ed predecessor it sports a matte black finish and Google’s trademark G, Oh and it’s also getting some small tech and feature improvements.

Google says the new Chromecast is 15 per cent faster, allowing you to stream 1080p content at 60fps, a decent improvement over last generation’s 720p. The new Chromecast is also getting the ability to act like a Chromecast Audio and let you play music in sync with other speakers connected to Google’s smart devices; that feature won’t launch until later this year, however.
