I bought this today. I am not sure this would normally be my 'thing' but it was 100% micropay and I planned to (and did) spend the micropay immediately on some other stuff, so I wound up with like ten books for my $16 bucks. And with the buywise club sale going on, I actually got back in micropay almost a dollar more than the cost of the book.
The iPod Touch has revitalized my reading. I feel okay with trying different books like this because I know I will not have to sell them back to the used bookstore due to storage space issues in my house. I can try as many books as I want and have them all forever
