There's nothing stopping anyone from reading and enjoying ebooks on their KT with whatever generation of firmware they currently have as long as the don't obsess over unimportant details. Updates are nice to have, not a necessity.
Can you imagine buying a paper book to read and then checking every day to see if they have come out with a new cover, or a new font for the page numbers, or a whiter paper? Complaining that you have to start the book over because of the changes? Just read the freakin' book!
