The good: The Roku 3's excellent new interface and faster processor makes it feel quicker and more responsive than any other streaming box. More than 750 channels are supported, including Netflix, Amazon Instant, HBO Go, Hulu Plus, Pandora, MLB.TV, Amazon Cloud Player, and Vudu. It also has cross-platform search that scours several major TV and movie services to find content. And Roku's nifty new remote has a built-in headphone jack that lets you listen without disturbing others.

The bad: There's still no official YouTube channel. Some services have an outdated interface on Roku compared to other streamers. The Apple TV still works better within the Apple ecosystem. And the Roku 3 isn't a great option if you're mostly looking to stream your personal digital media collection.

The bottom line: The Roku 3 is the best streaming-video box yet, with tons of content sources, lightning-fast performance, and an innovative remote with built-in headphone jack.
