Why did Nintendo chose not to implement a system wide achievement system? Stubborn or missed the boat?

I think it's out of stubbornness, like why they turned up their nose at the internet for so long.

I think they're just mad because they didn't think of it first. Meanwhile they're only prolonging the inevitable since they WILL have to implement it one day.
