You don’t have to buy a Kindle to read Amazon Kindle Books. I love them. Now, I don’t go around being green. If I am environmentally friendly, it is because it makes sense from an economic sense, and reading Kindle books is cheaper.
First, most of the time, the book itself is cheaper.
And you don’t have to buy the Kindle. I already have a Netbook (okay, I have two), and I have an air card, though that isn’t necessary, you can download the books when you are at home.
Not having the books fill the shelves is great. Being able to make the type size any size I want is even better.
Even better, is not having books that end up in the landfill.
