@sybren When this happened with Sony, they did a deal to transfer them over to Kobo. It was really seamless and worked great. I didn't lose any books and I remain a Kobo customer to this day. The world can be better! (And ePubs are hella crackable.)
The thing is, IMO once you buy something it should be yours, regardless of whether the original manufacturer decides to disappear gracefully or abruptly.
