If you haven’t heard of the Raspberry Pi you are missing out on one of the most unique and wildly successful uses for Linux. I use mine as a media server and it runs 24/7 for a couple bucks a year (if that) worth of power and will play any video, audio, or media I throw at it. Plugged into my TV with hdmi the Pi doesn’t even need an internet connection to work for a media server.
I can also boot to a Linux version for the Pi and browse the web or most anything else I can with a computer. In fact I am writing posting this on my Pi right now using a wireless keyboard with trackpad. As you can see it is a pretty nifty little device and super portable. The best part is, for around $50 buck you can be enjoying your Pi.
