Are you ready for the answer? You've probably been sitting on the edge of your seat since the last post, wondering about this game-changing ereader factoid. Get ready, it's coming. . .

First let's go over why we buy books- not why we read books, but why we buy them.

1) To read them
2) As gifts
3) To put them on display in our bookshelves and pretend that we read them.

On the Kindle, why do you buy books? Right now, you can't give a Kindle book as a gift to a friend. You can give them an Amazon gift card, but that's as close as you can get. You also can't display your Kindle books on your book shelf as a testament to your erudition. So that leaves us with *reading*. You buy Kindle books to read them. Period. End of paragraph.

With that established, let me present you with two scenarios. Scenario 1: you buy an ebook for around $10, read it once, like it, and then it sits on your Kindle. You can't lend it to a friend, you can't put it on your bookshelf. It just sits there. Scenario 2: you download a book for free, read it, like it and after a period of time, it disappears from your ebook (unless you download one of Google's free public domain books and then it's yours). For the majority of your ebook purchases, which scenario would you choose?

Right now, for Kindle owners, the second scenario does not exist. However, for future Sony ereader owners, it will. Not only will Sony ereader owners be able to download Google public domain books for free, they will also be able to wirelessly download books from their local library for free. Free and easy. Easy and free. That's a game-changer. Period. End of post.
