Kindle. Limited space, and I have issues with throwing books out, or selling books. Sometimes I want to reread my books. Should I then buy a new one, or wait for a sale. Nah. Library can be good but If I want to read a book, and it's not in that specific library. Why waste time going to another Library. Makes my life easier. I am also not romantic about print books. It's a book, as long as I can read the story. That's all that matters to me. I buy books on sales as well. Plus it works well for someone with limited space.
