Chromecast

Trying a different tack than other internet-connected TV peripherals, the Chromecast ($35) from Google lets you wirelessly stream content from your device — a Chrome browser-equipped laptop, iOS or Android smartphone, or tablet — to your HDTV. With this tiny dongle, you'll be able to watch video from services like Netflix, YouTube, Google Chrome, and (with a forthcoming update) Devour on a full-size display. It's easy to set up, small, and capable of streaming content in full 1080p HD, with 5.1 surround sound. If you buy it now, they'll even throw in three months of free NetFlix, not bad.
