I loved stanza on my iphone. I used it a lot. I got used to adjusting the brightness by running my finger down the center and miss that in ibooks. But on ipad i will continue to use ibooks. Adding books to stanza is a pain. I have 500 books and have a 64 gb ipad. With the iphone i never minded moving a few books at a time but with the ipad it just makes sense letting itunes import all books. I really wish I could make folders inside ibooks though.
