Who wants Pi?
Whether you want to use the $35 Raspberry Pi computer as a media center, retro games console or desktop PC -- the credit card-sized device has got you covered.
But that's only the start of what the smash-hit machine is capable of.
As a board meant for tinkerers, who aren't scared of dropping down to the command line or breaking out the soldering iron, it's no surprise the Pi can run all manner of weird and wonderful systems.
This list rounds up the free systems that are available, from easy-to-use desktop systems aimed at novice users to powerful systems designed for those familiar with the command line.
