Please tell me again how the previous gen's 256/512mb RAM was more than enough for the whole lifetime of the console, that it managed to stay on par with pc games?
Edit: And I never said pc's dont need upgrades, but upgrading just your RAM when you need more RAM sure beats having to wait half a decade (or more)for the next gen to come out so you can upgrade your whole system
Why would someone want to do that? What a ballache. Rather just buy a new playstation or something every couple of years
