i bought a ps3 because it had linux.
at the time my computer was slow as hell, parents wouldn't get me a new computer, and couldnt get a job even in summer because of school rules.
so for christmas, i got a ps3, and rationalized a 600$ console as a bluray player, a game console and a better computer than i had.
you want to curb piracy, sell the games with a code in them for online play. i dont mind putting in a 20 digit code to go online with a game, as i never do.
this way ligit home brew can happen. and before you say home brew is a way around to allow piracy, take a look at xbox live indi, all that is basically homebrew. someone in school for game design, who wouldn't look at the ps3, and build a home brew game to show off their competence.
