The inability of being able to read on anything other than an iOS device is what has kept me from buying iBooks. With Amazon and Kindle I can read on pretty much anything I want to.

I had different experience with Kindle books. While the app is available everywhere, there are big differences in app quality and functionality (even restrictions) depending on platform.
For example: I bought a comic from the Kindle store for my kid. We could open it easily with Kindle app on an iPad and were able to zoom it to pages etc. Mac and PC desktop Kindle apps refused to open the comic in general, telling us it being not supported on these devices. Surface Kindle app on a SP3 from the Windows Store could open the comic, but we could not even zoom on it, which is ridiculous.
Even general functionality of Kindle apps is not equal on different platforms. All this DRM-based crap turned me off Kindle store for good.
iBooks, on the other hand, do also have DRM, but once you bought a book, you can read it on your Mac, iPad, iPhone without limitations. At least, from my experience.
