from that review

electronic ink displays have an advantage over the iPad: their displays have higher contrast and resolution.

You have to peer very, very closely at them before you can even detect the dots that make up the letters. The iPad’s type is noticeably less smooth. But it’s still not jagged. It’s perfectly comfortable to read. The iPad has something that e-ink displays lack, too: backlighting. The LCD display wouldn’t work without it but it has the nice side-effect of providing your iBook with a built-in reading light.
