Ebook acceptance isn't exactly universal. The main motivation for me in buying a Kindle was being able to store books in no space at all, but I'm finding that electronic books aren't all that useful when it comes to reference, cookbooks, DIY, and other sorts of books that I might want to read and re-read. This is why I'm searching for a reasonably priced paperback copy of V Is For Vengeance. I've got all of the Kinsey Millhone books through U and want a complete paperback collection. I enjoy re-reading these books every few years.
I'm mostly putting escapist fiction on the Kindle - the sort of thing that would ordinarily end up at Paperback Trader or in the donation bin at the library - along with a lot of free stuff that I may or may not like. I'm much inclined to buy a hard copy when I come across a book that I really enjoy. If it's any comfort, I doubt that real books will be entirely supplanted by ebooks in our lifetimes or even beyond.
