My understanding is that e-ink with higher than 300 dpi is very difficult to produce which means it is rather expensive and doesn't look that much better to most people. Additionally, people think of an e-reader as a sub-$200 device so the market for a premium high DPI e-reader is just rather small. People are already complaining about the price of the Kindle Colorsoft, think what they would say if amazon put out a Kindle high DPI and it was in the $400-$500 range.
