I guess Raspbmc Is the most suitable for me.
What attracts me the most It’s auto updating, meaning you constantly get new features, performance and driver updates. You can however turn updates off at any time.
Certainly, when I read this on Frodo the next XBMC release – what’s next
XBMC has support to compile for the armhf platform. Small ARM systems like pandaboard and the raspberry pi should be supported then.
Still do not know when Raspberry Pi will be sent to me,So I have the time to wait for the release of Raspbmc or/and Frodo
