Let's say I want to buy an Ebup from BN to my Kindle or vica versa. I just put in the DRM-free Epub to Calibre and get out an identical Mobi file, right? And vica versa.
I hope both of them go DRM-free by now, right?
In my dreams? Really, just how these two of the most popular e-book formats are compatible with each other? Do they remain identical by converting from one another?
