Congratulations, you're an author. A billion people can see your ebook on Amazon. Great.
How about giving me, and a few others without a Kindle a chance to buy your books.
So far I haven't downloaded any books from Amazon, but I'm told that if an ebook is listed as "
Simultaneous Device Usage: Unlimited" that it isn't DRMed and can therefore be converted to a format that I can read.
You do have the right to have your books DRMed, and I have a right to not buy them in a format that I can't use.
Your choice.
UPDATE
B.Tackitt in post #21 has better information on "unlimited simultaneous usage" than I had.
UPDATE 2
"
Simultaneous Device Usage: Unlimited" may, or may not be DRMed. Sadly there is, as of now, no way to tell if a Kindle book has DRM on it or not by looking at the web page.
