OnLive's Microconsole TV Adapter went on sale yesterday, with units expected to begin shipping the first week of December. It consists of a smallish black box that acts as a go-between for the OnLive service and your television, allowing players to stream PC games directly to the television without need of a PC.
The $99 device comes packed with a controller that looks a PlayStation 3 controller and Xbox 360 controller had a baby, a power adapter, a network cable, some batteries for the controller, and an HDMI connecter to hook to your television.
This should be all I need to stream OnLive games to my television.
I'll be testing out how well the service works via the Microconsole during the coming weeks, so stay tuned!
