RaspberryPi: OpenELEC
OpenELEC (short for "Open Embedded Linux Entertainment Center") is a free and open source embedded operating system providing a complete media center software suite that comes with a pre-configured version of XBMC and third-party addons with retro video game console emulators and PVR plugins. OpenELEC is an extremely small and very fast booting Linux based distribution, primarily designed to be booted from flash memory card such as CompactFlash or a solid-state drive, similar to that of the XBMC Live distro but specifically targeted to a minimum set-top box hardware setup based on an Intel x86 processor and graphics.
