If I understand the Kindle correctly, it would be perfect for someone who wanted to collect out-of-copyright books. I understand they have a large collection of them themselves that users may download at no extra charge. Their value proposition is that most people want current writings, and that’s probably pretty accurate. But someone like you could REALLY take advantage of it.
I’ll have to look into that later this summer. It’s still way too expensive, but when the price drops $100 or $200 I’ll probably be buying.
