I like this,  one thing that annoys me about ebooks is they are almost (or sometimes the same) price as printed ones, but you can’t easily lend it out to someone, or resell it, etc etc.  And they have to be tied to an account.  This could be a nice workaround so when you finish the book, you can lend it to your kids to read.
