First, why Choose OpenelecRASPBMC the volume of large functions, the corresponding speed and performance to be weak; Openelec is a lite version, small size function, the corresponding speed and performance have been improved. This depends on our choice, if you like me with multiple sdcard to play Raspberry Pi, then use Openelec as a home Media Center is the most suitable.It is small in size, please refer to
