Got my aunt a Kindle about four days ago. She hasn't touched it aside from going through the user's guide, so I used it a little in the past couple days just to get in-the-know, I guess you could say?
Found Pride and Prejudice for 99 cents, Les Misérables was free, got Fight Club for about 9 bucks (though I know quite a few books can be found for free on Amazon, or even 99 cents, I'm still unsure why this is. I realize they don't have to print paper/use ink/etc, but still, I'm very iffy about it all. Guess I should do some reading on the business aspects of how that's possible). Been getting into it, really. >.>
