Boxee Is XBMC with Newer Look and Social Flair, and many new functions.
boxee is a social media center. with boxee you can play videos, music and pictures from your PC or from the Internet. you can also share with your friends what albums you're listening to, what movies and TV shows you're watching, send recommendations and more.
boxee is designed to work with a remote control (it looks great on a big screen TV), but you can also control it using your keyboard.
once installed boxee will start scanning your local Movies, Music and Pictures folders automatically. boxee will attempt to bring artwork, reviews, cast, etc. for your media, so browsing your library becomes more useful and fun than looking at a list of files.
boxee is based on the best media center on the planet, xbmc.
