Okay, also good to know. So, you've never purchased a Kindle ebook? Probably because all the books you've wanted were available as iBooks, right? 
Hi Scott, Right. Although several years ago when Apple bookstore was starting up, they didn't have all book distributors signed up, so not all books were available. Now I think they may be past that issue as it seems all/most books are there. I think Amazon books are less expensive and Kindle and Kindle App are great. But I guess (for better or worse) I am deep into the Apple eco-system in my personal life. Music, books, videos, apps, podcasts, etc. Good thing is when I purchase something all my iDevices automatically get synched and song or book or whatever magically appears on each. 1 click - fire and forget, backed up in cloud. Look Mom, no wires! Hahahaha! :) Dan
