What is very cool is that the highlights I have marked whilst reading (and this includes notes I make) show up on this page. It isn't always immediate, but they do show up. Very cool for saving stuff I want to use for review and/or discussions and I can copy and paste from my screen onto whatever I'm writing and save time and typos.
I'm not sure how much of these notes those not logged into your Amazon account will see, but I've attached a screenshot so you can see what I get with the highlights. Sorry, but I don't know how to make the attachment bigger for you
