Thank you for the very helpful replies.
So I have a few more readers to take a closer look at, and being that I'm not 100% convinced this technology will be for me, it sounds like I could benefit by also sitting and waiting to see what happens in the next few months. Don't get me wrong...I would figure a way to use it. And I think I would like it. But I haven't converted yet and can afford to wait. Having realized how robust the library is right here, this whole issue about buying books might not be such a huge issue. I've already found plenty to keep me busy for a long time.
I had wondered if anyone offered a service similar to Netflix...charge a monthly rate to have X number of books out at a given time. Believe it or not, I think THIS would be the ideal way to read for me. Maybe it's not profitable...I dunno. But I don't hang onto my books (except cookbooks) and I think a membership service would work well for me.
But it sounds like there might be some library download options. In PDF format. So I'll have to check that out, too.
