Okay, back when the PS3Jailbreak community was in its infancy and when I used to be a member at psgroove, not psx-scene :P, I remember a lot of people wanting to install alternative operating systems on the console. I remember seeing people installing windows xp and 7, but it had painfully slow start up speeds amongst other things. The consensus was that it was get it to run smoothly on the ps3, as it was ARM based,which uses reduced instruction set computing, while intel/AMD chips uses complex instruction set computing.
BUT Windows 8 is being made for ARM chips as well CISC chips, since they're introducing win 8 to the tablet market. Just thought I'd mention it, seeing as it may lead to some interesting work.
Feel free to move or delete if you think this is 'lame' :P.
