My conclusion with a self-published book a number of years ago was that, once you get beyond flowing text, creating a Kindle version gets a lot harder. It can clearly be done--e.g. there are Kindle format guidebooks that work well. But when I did another self-published book a few years later, I was giving it away anyway so I just did a PDF version for tablets. (My last one is through a publisher but it's also mostly text.)
