I have been reading ebooks almost exclusively since I bought my Kindle. I am totally in love. I never would have thought that I would prefer ebooks, but now that is my favorite format. It's just so much easier to read on the Kindle because of the font size and how light it is. I can turn pages with one hand. Also, I can switch from one book to another with two clicks and I never lose my place.
I'm actually planning to get rid of most of my print books, not all 16 bookshelves full, but a significant number. I'll keep my cookbooks, reference books, signed books and a few others, but that's all. I never re-read fiction, except for a few classics, which are all available as free ebooks, so there's no need to keep any of it.
Now I have to figure out the best way to get rid of them all without going into business. I've ruled out donating to the library (long story, but I do have a reason) and there aren't any used bookstores that pay cash rather than give credit. Hmmm, looks like I'm going to have to do some research on this.
