The Roku 2 XS, despite its name, is actually the fourth iteration of the Roku. What started as a small, cheap box to stream Netflix to your TV has turned into an absolutely tiny box that streams Netflix, yes, but also a whopping 300 other apps, from Hulu Plus to Pandora to Rdio to MLB to Fox News. Those apps work essentially like any other app store: You can browse the store either on your TV, using the Roku's remote, or you can do it from a web browser. The apps are mostly free, but the good ones (Netflix, Hulu, MLB) require a separate subscription--the Roku itself, needless to say, doesn't require a monthly fee of any kind. The Roku 2 comes in three versions, the highest-end of which I tested. That one, the XS, comes with a Wii-like motion-sensing controller which can be used to play Angry Birds on your TV--the first time to my knowledge that those birds have graced a TV. The remote is actually compatible with any of the three models, but is included only with the most expensive.
