With the Roku Streaming Stick, Roku has condensed its popular media playing box into a small USB stick that can be plugged into a TV (provided it has a USB port) to access a range of streaming video services.

The Streaming Stick supports 1080p HD video streaming, offers built-in Wi-Fi and draws power directly from the TV -- no external power cords required. It can tap into the full content library that the traditional Roku boxes have access to (Netflix, Hulu, etc.) and is controlled with a Roku remote. The stick costs $99, but there's a fairly large catch: only TVs with USB ports that support MHL will be able to work with the Roku Streaming Stick. To date, that's a fairly limited selection (Roku lists two TV vendors and one projector on its site, as of this writing, that support MHL).

Given this limitation, and the cheaper, more universally compatible alternatives from Roku, reviewers weren't all that enthusiastic about the stick. It works well if your TV happens to have MHL-enabled USB ports, but that's a very small audience indeed.
