Two observations about the Kindle
Or maybe three, because number one is I love it and wouldn't be without it. That said ... it's perilously easy to buy books for it. That One-Click can add up. And second, once you have bought them, they aren't a stack on the coffee table, which means that the virtual stack can tower very high, and you'll probably never actually get around to reading them all.
But at least you bought them - so the author gets paid.
