Whatever "carbon footprint" these devices may have, they do save trees, don't they?

I love to read but hate to buy books. I'd rather save the money, and I have no interest in accumulating stacks of paper and binding that I am unlikely ever to re-read. I'm not a collector ~ of anything.

My strategy has been to patronize the library regularly. As an old dog with some degree of resistance to new tricks, I may not ever switch over to electric books, but then again I just might.
