An immediate hit with consumers, Google's Chromecast dongle is a great gadget for students to own.
The dongle is a dirt-cheap way to stream media to your TV from a number of devices. Chromecast is cross-platform, and so is compatible with iOS, Android, Windows and Mac. Once plugged in, you have to install the Chromecast application before streaming PC and mobile content including Google Play/TV, YouTube, Netflix and potentially services like Pandora in the future.
