The second-generation Roku streaming video boxes present themselves in an impossible-to-resist, palm-size package and feature even-harder-to-resist pricing. Starting at just $49, the Roku LT offers high-definition content from the likes of Netflix, Hulu Plus, Amazon, HBO, Pandora and more streamed directly to your TV set. The high-end Roku 2 XS costs only $99 and offers some nice extras, such as 1080p video, a motion-sensing controller and the full edition of Angry Birds for some big-screen pig-toppling action right from your couch.
