It also deleted all my side-loaded books. That was the last straw for me. I only buy DRM-free media from now on and only use respectful hardware. I use my Remarkable 2 primarily for e-reading now, though I concede fully it's not the best user experience for reading. But I don't have to worry that it will delete my books! I can also now "write in the margins" which I've found to be a powerful way to take notes. I can't bring myself to write on physical books, but with Remarkable you can have a copy that is stock and a copy with your notes on it. Best of both worlds!
