Really... how many of those angry people in the CAS did install Yellow Dog Linux and actively used it on a regular basis? With satisfaction?
I bet none. Due to the memory restrictions it was dog slow, also because the SPU's weren't utilized by many applications, making it a pretty slow performer. And that's what OtherOS gave you, a very restricted space in which you could install linux but it didn't gave you a great, powerful machine with Linux to use as a desktop machine.
that's the sillyness of this. Some people cry like a little baby that their life has no meaning anymore because, oh the horror, OtherOS has been removed from the _play_station!.... A group which is really stupid among those crybabies joined forces with a group of shark lawyers to sue sony to get some money. For what? all the damage that was inflicted upon them by the removal of this marvelous option called 'OtherOS'? Gimme a break.
If you want to run linux so badly, buy an ASRock with a BR drive, install linux and be happy. Oh, of course, everyone in that CAS was part of a supercomputer project, right? ...
