Oh, I forgot to reply to your comment about magazines. I subscribe to Self Magazine, and they give exclusive content to their subscribers, too. I was looking at my first online issue last night on my iPad. It was really neat. Makes the paper version rather boring!
I have a Nook Color and a Nook Tablet as well (I'm going to have to sell something!) Looking at a magazine on those is not as nice as looking at it on the iPad.
