The energy used to create the material actually *is* the energy stored. Think of it as a very tightly wound-up spring.
I think the reason we only see high DPI in cell phones and MP3 players is because the viewing distance is much closer compared to a computer. Didn't bother to read the article, but does the author take into a account the eye's ability to see detail in terms of arc? At a typical viewing distance for a laptop (100-140dpi) looks pretty smooth to me (20/20 vision). I'm not sure there is any benefit to 200+ dpi on a computer display at typical viewing distances.
I've devised an algorithm that tells me with 100% certainty that this guy's ego is way too far up his ass.

Scientists working in the UK and China have closely examined the fossils of multiple theropods and actually found the colors and patterns that were present in the fossilized proto-feathers. So far, the answer is orange, black and white in banded and other patterns. The work also thoroughly thrashes the idea that fossils might not be feathers, but collagen fibers instead. If this holds up, Birds Are Dinosaurs. Period. And colorful!"
