Absolutely. I have selves filled with books. I have had to downsized a few times because the books had overtaken everything. I received a Kindle as a gift and saw it as an opportunity to be able to carry with me a great many more books than if I was boarding a plane with one or two, etc. There was also a time when I traveled by automobile quite a lot....an average trip would be anywere from 4 hours to 7 or 8 hours.... audio books were very handy.
So, for me.....I like them all because they fit into different areas of my life quite nicely.
