Roku has three models, the $59.99 Roku HD, the $79.99 Roku XD and the $99.99 Roku XDS. Every Roku player can support HD video and includes built-in Wi-Fi. The Roku XD and XDS also support 1080p HD video and Wireless-N Wi-Fi. The XDS, our Roku of choice, also supports dual-band wireless and can play music, videos and photos from an included USB port.
While not as small as the Apple TV, the Roku still has a very small footprint and can easily be tucked out of sight.
In the past year, Roku has really raised its game when it comes to supporting more types of content and services. Because it's a streaming-only player (unless you use the USB port on the XDS), content is all sourced from the net. This means that new channels are added via free software updates.
What we like about Roku, however, is that unlike some other set-top box solutions, the interface and video are made for use with a remote control, offering easy access from the couch or the bedroom.
The new Apple TV is a nice device -- but it only supports iTunes, YouTube and Netflix. Google TV has potential, but it's expensive and it's blocked by virtually every major online producer. The Boxee Box shows great promise, but it's still working out some of its kinks and costs $100 more than the Roku.
If you want to watch Netflix, peruse Hulu Plus, rent a movie or TV show from Amazon, tune in to live sports content and listen to streaming music services, Roku has you covered.
