I bought a ipad for Christmass and wanted to buy individual e-news paper or magazines and only could do that at Barns and Noble, so I downloaded the nook app to my ipad.
I established a account and I am happy!
You need to get on the internet and download your book and a then pop up message ask you want to open in ipad or nook.
Same way when downloading Investers Buseness Daily pdf, pop up message ipad or nook.
You can buy your digital content from "ANYBODY" with Ipad.
Main Point: Barns and Noble is a strong contender when concidering their e-content for sale, and you don't need a nook reader to read it.
