However, LCD is still LCD, an Qi is an LCD. The LCD screens will eat up energy and the pixelation will make it more difficult to read than e-Ink. By pixelation I mean the space between the square pixels which causes our eyes to view a series of horizontal and vertical lines which our brains have to gloss over. It causes eyestrain for prolonged reading.

Pixel Qi should be considered an improved LCD rather than an eInk replacement. Its reflective mode means you can use it in bright light while realizing 80% better energy efficiency, and also some energy savings in its 'transflective' mode. It will improve laptop/netbook/tablet versatility and performance modestly.
But I don't think it makes much sense to have this on a dedicated ereader device. If you've got that screen, and the hardware to drive it, it would be perverse to artificially restrict device functionality to the single purpose of reading ebooks. Besides, Amazon would want to sell you MP3s and videos to go along with ebooks, and that argues for a general purpose device - and I don't think Amazon has the credibility to put their brand on one.
I don't understand your point about pixelation. Are you saying the screen has insufficient PPI as compared with e-ink? Based on what? Current eInk is between 150ppi (9" screen) and 200ppi (5" screen). Meanwhile LCD PPI in ranges from 133ppi to over 200ppi over similar sized screens, even higher on smaller screens. So I don't see there's much of a generalization to be made.
