Who cares? Do you call newspapers to complain that they print on newsprint?
Newsprint? Damn, might as well spend some time making a time-machine so I can go back to 1983 when newspapers were still relevant.

Magazines and first editions aren't printed on newsprint. Yeah, I'd prefer not to read grey on grey.
The font issue hasn't been resolved because the screen is too small to allow much zooming without significantly sacrificing the page composition.
But you can absolutely install other eBook formats, either via USB or by downloading directly from the builtin web browser, neither of which costs anything, and does not pass through Amazon's hands
Ok, that I wasn't aware of. I was under the impression that the Kindle didn't support other ebook formats out of the box without a conversion process. This certainly makes the device a little more capable.
