The prime reason why people are pissed, regardless of how well the system functions is that when Cerny revealed that the RAM figures had been doubled (for the people who closely followed VGleaks) in Feb, most of us thought it was to aid gaming side of things (given how the machine has been marketed so far). However, now we find out that the upgrade was mostly for the sake of non-gaming related multimedia functionalities.
So, in essence, it's all about perception and its supposed violation.
Given I've cooled my jets, I do understand that the OS still incomplete and much like it was with PS3, with time, the footprint of PS4 will change and only for better (on gaming side of things).
Time is the best healer and perhaps by launch, all we'll ever care about are the games (and their visuals, etc).
