I have a nook and absolutely love it. I chose the nook over all others because of the ability to share books with friends. I don't think the ipad or Kindle offer that ability.

I love reading the physical books too because I liked to see the progress of the bulk of the pages moving from the back cover to the front cover as I read along. One of my concerns before the purchase was not being able to physcially SEE or FEEL that progress. But, the little progess meter on the bottom of the screen feels the need.
