Yes, I know they're always available to download from Amazon again, and I always have Kindle for PC on all my computers, but 1) I don't trust that there will never be glitches or they decide I no longer own the books; and 2) I'd hate to have to download almost 1000 ebooks in the event I should ever lose my mind and buy a Kindle
. So I will always prefer to also keep my own copies available, especially since space isn't a problem for ebooks.
