I don't care if the OP comes back to this thread, we are doing fine without him. LOL
I switched to ebooks for several reasons. Free and low cost books being one of them. Another reason is because I have lived years and years outside the urban setting and the closest bookstore would be an hour or two drive away. I ordered a few physical books through Amazon, but I also hated having boxes upon boxes of books to move or sort through when we moved (often).
Looking back at the bookstore experience for me, I realize I was never really comfortable looking to buy in a bookstore. I did it, yes, but I hated having people around me, possibly judging what I am buying. Not that I cared, but I just hated the feeling of others around me during what I consider to be a very personal experience. And the bookstores in the areas I have lived were not always the greatest, often having more videos, music and games than books.
