I read a lot. I'm fond of bringing books with me to pass the time when there's time that needs passing - for example, on an airplane, waiting for a bus, on a train, etc, and of course also for leisure at home. I read quite quickly, which means that if I bring a book with me to kill time it's likely that I will finish the book and still have time left over. With paper books, this meant that I would find myself lugging several books with me at all times, which is rather inconvenient (especially if it's a book I could only get in hardcover!)
So, I got a reader so that I could take multiple books with me anywhere without taking up all the space in my bag, and without being murder on my back. And I must say, I absolutely love it!
It's also nice because I can be a bit fickle with what I read, so if I start reading something new and don't like it, I can stop reading it right then and still have hundreds of books to choose from. XD
