Re: FAO Wally
I could understand using the things with render farms and the like sure.
I guess if the things were cracked and a flavour of Linux could be installed then it might be doable. I don't know much about the systems either but, even though they are as close to typical PC x86/x64 hardware as they have ever been, neither MS or Sony are going to make it easy to put your own operating system on them.
So I doubt you'll be able to stick Windows/MacOS X on them any time soon.
