I would disagree with the last post. The most annoying thing about reading on the web is the glare from the screen. Thats what the Kindle solved for me. I used instapaper but it make me download the AZW file which was almost as much hassle as cutting and pasting it myself. I switch to
clipDO.com when I saw then launch on eBookReader.
There are things I would change about it but at least the delivery is instant (or near instant)
