Anytime you see something that's relatively easy to solve by a major company but remains unsolved, either you don't realize how hard the problem really is, or the company is profiting from their "oversight". Apple could easily make a 2-disk-drive macbook, but they don't sell that configuration.

I'm not so sure in the case of Amazon. Their requirements analysis process appears immune to customer feedback.
