Maybe, but any computer nowadays puts PS3's RAM to shame. All the PS3 has going for it is it's CPU and GPU (which are admittedly, GODDAMN INSANE).
tbh, Sony could in a handful of years, not change but just add in technological improvements to the PS3s components, shoehorn a respectable amuont of RAM in (4GB), and basically sell a Mac style PC, at one hell of a price point. I'd get that PS3.5
Unfortunately, it'd rely on Linux to stop masturbating over itself and start becoming useful to the average computer user. (see today's XKCD)
