An immediate hit with consumers -- and sold out in many stores -- 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 enabled, and so is compatible with the iOS operating system, 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.
High-tech or plain annoying, an alarm clock is a necessity of life for the average student. Clocky was my saviour and bane through college -- as difficult as I find it to get up, I found myself suddenly flying out of bed moments instinctively before the alarm began, which sends the clock in flight to zoom across the room and zip around until you catch it.
I eventually caught it and threw it across the room in a rage, so the only improvement I would make on lesser models is a shell tougher than plastic.
