To be fair, a lot of general use people know their computers run Windows, but if you ask them what Operating System is installed, they'll hem and haw. Quite a few don't even know the difference between RAM and HD space. This isn't to say they're dumb, they just use their computer the way it's been intended to be used by the common user; as an appliance, like a microwave, that does what they need when they need it, and nothing more.

It's the major reason why we need to have such a length of backwards compatibility. If you weren't sure what your RAM was, would you have a good idea of when to upgrade or why? Probably not.

Again, they're not dumb, they're just put on this earth to make our lives a living hell. They fulfill the balance.
