I vastly prefer ebooks for pleasure reading. I read them on my phone (white text on black background with the brightness waaaay down). It's great because I can read anywhere - in many places that I normally couldn't, because 1) I always have the book with me, 2) I only need one hand (in fact even that only occasionally since you can set the 'book' down without having to go to great lengths to keep it open), and 3) I can read in the dark without disturbing my wife.
That said, I would never want to try to study from an e-textbook. All reference books I still buy in print. You would think with their searchability, ebooks would have an advantage there, but I've always just found it too awkward trying to jump between sections. It's much easier to have a mental model of where information resides in a physical book than a digital one.
I also have some fiction ebook on my phone ready. It's big advantage is that it always with me. Statistics tell me I have read 35 books in 163 hours so far. Never tried reading non-fiction.
