Query: Why not?

I just placed an order for mine last night and I can't wait for it to arrive. I'm not sure how I feel about all the features yet since I haven't seen one in person, but I ordered anyway. With the free shipping and amazon's 30 day return policy I figure I have nothing to lose but some time if I don't like the way it works! I saw that books ordered are also returnable within 7 days of purchase, so that gives me a solid week to decide whether or not I like the product. I'm really excited to have instant access to that many books at once, usually I carry a pile of books with me and this will (hopefully) really reduce that load.
