Yes I agree, miniaturized gadgets probably appeal more to women, whereas men like traditional old school stuff. I personally like laptops and PC's, but I dont own a tablet, nor do I want to, I see no use in them.

As for a quantum PC, I highly doubt it, this is not a question of efficiency, but a question of physical limits. A QC requires too much energy just to maintain the quantum state, not to mention the calculation part itself. I think it will only be used for large scale research projects, and by governments, but hardly by mainstream.

I think most of those documentary films are wishful thinking, they like to assume things in the future that just wont be true.

But who knows maybe I'm wrong.
