Okay I have about 900 Kindle books that I've paid for. I've never dared try stripping the DRM off them in case Amazon somehow finds out and blocks my account, losing me the rest of them. But since Amazon's planning on deprecating my Kindle in May now I guess I have nothing to lose. What would everyone suggest? And can anyone recommend a good e ink reader to replace the Kindle that can read files from any source?
@afewbugs There are Android ereaders that allow you to use apps for almost any source of books. Something like the Boox Go 6 might be a good device for you. I've had a Boox Leaf for 4 years and have been very happy with it, but I'd recommend doing a bit of reading about the devices so you know what the limitations are.

@afewbugs Another option to look at is Pocketbook, which is a European brand more like Kobo, but not tied to any one book store. Some of the newer models have access to Libby included, which is useful if your library service offers ebooks that way.
