Yeah, I'm thinking something like this, but from what I know faster RAM wouldn't have been much more expensive, especially in bulk for manufacturing that Nintendo would purchase them. And, correct me if I'm wrong, RAM has actually been one of the better qualities of past Nintendo consoles.
This is just really slow, super cheap RAM seemingly not suited for the kind of console they're making. Slow PC RAM dumped in a console box, not good for handling textures and assets, and limited in comparison to the Xbox 360 and PlayStation 3, even when considering the quantity.
I don't know. My technical knowledge has it's limitations, so like I said I feel like I'm missing something. But everything about this, more than anything, screams aimless and dumb to me. And I guess that's just how it's going to be.
