How many people do you really think were running linux on their PS3's?? I would place a wager that it was less than 1%. Probably like .1%
I tried it once a few years back when i was without a functioning home computer, I quickly found out that the version of yellowdog linux i was using required a progressive scan TV in order to work. So i restored the original PS3 OS and never looked back. Linux has a low adoption rate even among PC enthusiasts, how many console gamers even know what Linux is? I'm more annoyed and perplexed by the complete removal of PS2 compatibility on the PS3 slim while at the same time continuing to include the virtual memory card creation utility.
