When the ability to make books for iBooks came out I was excited. I would like to write a math textbook with embedded videos in it. I was about to explore doing this in iBooks but then I realized that I would be limiting my audience to those with Apple devices. I abandoned the idea.

I buy digital books from Amazon and not Apple because I know that Amazon will make its books available on any device. As far as I know iBooks are not available on non-Apple devices. Why would someone lock themselves in? If they made their digital services device agnostic I’d buy from them.
