I own a Kindle , 3 original Reb 1000 series , 2 generations of Sony Ebooks and the Edge.........I find that the Edge may be just slightly slower in page turns than the Kindle ( which is also slightly faster than the Sonys ) but hardly noticeable and since the screen is so much bigger, not to be unexpected...I don't own a DX but I would guess that page turns would be on a par with the Edge. Maybe there is something wrong with your edge if the pages are turning so slow.
