“Access your Kindle books even if you don’t have your Kindle with you”
“Books you purchase can also be read on a Kindle”

So we can already legally have two copies of the one purchased book; one on a Kindle e-reader, and one on our pc.
(I don’t really want to copy any Kindle book, just transfer it from my laptop to my Onyx Boox M92. If that can’t be done, I’m willing to remove the book from my laptop after copying it on my e-reader, so I only have it on the latter. But of course this is nit-picky. Amazon should make it possible to easily move a legally bought book from one reading table to another, whatever that "other" is, even if it is not a Kindle. Luckily info on how to do that -stripping DRM- is easy to be found.)
