This software is extremely popular at the moment, using it you can stream movies, TV shows, music in fact anything. Raspberry Pi is not ideal for running XBMC, but does the job more than adequately.I have XBMC installed on my laptop and it only works marginally better. I've also seen XBMC on some of the hardware boxes you can buy to turn your TV into a smart TV. Or at least that's how they are advertising these boxes.
It won't be long before someone spoils this situation. Like Napster, it seems that all good things on the internet come to an end. The authorities can't stand us using unregulated software and stamp it out when they catch up with us.
