i am thinking of installing this on my ps3, my question is that should i alott 10 gb to xmb or linux? i only used the xmb to play my games and saved game data and occasionally download demos... can i download torrents and watch movies on ubuntu? and i have a bunch of blu ray and hd movies in mkv format on my computer, i know the ps3 cant run it, but if install vlc on my ps3 and put the mkv file on a dvd, can i still watch it in ubuntu? and lastly if i do decide on alotting 10 gb to xmb, is it possible to go back and change it? and is it possible to uninstall ubuntu? oh and last question, which is more user friendly and better overall, ubuntu or yellowdog or fedora?
