On top of all of that, nobody's going to revise the book out from under me while I'm reading it, or prevent me from loaning it to a friend, or even yanking it entirely from my device.
As far as I know (in the sense that I've never experienced anything like it in a decade of using a Kindle) that the book's getting revised from under me while I'm reading it. There's an occasional update for some books, but I have to actively choose to download the updated version, otherwise my original stays the same. I think I've only downloaded an updated version a single time.
