The free Boxee Media Center, based on the XBMC project, plays just about any local content but it’s specifically tuned to handle internet media streaming sites such as Hulu, CBS, Comedy Central, Last.fm, and flickr. Not only that but it has a social networking aspect that allows you to recommend media to your friends.
Currently it runs on Linux, Mac, and soon Windows. With a simple hack you can also run it on an AppleTV, which then turns it into a fully blown, unrestricted media player.
It’s enough to make you think twice about keeping the cable TV. Sign up for an invite here.
