The problem is that the DX is not a good Kindle from Amazon's perspective. Note that while you're requesting your "printed page" to be printed page size, they're focusing on a "book" that is book sized. From Amazon's perspective, a great Kindle is something that you use extensively, carry with you everywhere, and buy many books on. There are very few books that Amazon sells that are seriously helped by the DX's larger screen, save maybe for someone who needs to crank the font way up. The DX, I assume, is great for PDF's with formatting/figures that won't convert well (which the small Kindles are pretty bad at). But Amazon makes no money on you reading PDF's on your DX. A DX with a great touch screen and a stylus could also make an outstanding replacement for paper that you write on. But again, Amazon won't make money for each page you scrawl. Add to that the fact that the market for the DX is presumably significantly smaller, and you get where we are now. Amazon charges a lot for the DX because they need to actually profit from it, instead of relying on content sales. Amazon doesn't have a big incentive to improve the DX because it doesn't make them much money. Maybe in the long run, they'll get around to it, especially if technology does get to the point where you can make really good lines on e-ink. Then maybe they'll push for the Kindle to be the digital piece of paper that everyone owns, and oh by the way, now that you can buy content from your paper, maybe that will be some very profitable paper for Amazon. But right now, the incentives don't align.
