I would think that Amazon be happy that you had replaced the Nook with a kindle.

I doubt that they will waste much effort on the legitimacy of books bought from other sellers.

AFAIK they do not have a legitimate method of determining where you bought books and whether you stripped the DRM.

To accomplish this it seems to me that they would have to access and examine your actual ebooks and if the books were purchased elsewhere (not overed by Amazon's TOS if it even covers this for the books they sell) it could constitute invasion of privacy and even be contrued as piracy.

Perhaps Barnes & Noble could examine a book purchased from them on the kindle but I doubt that Amazon would help.

Overall I question the legality of using your bandwith to examine books on your device.

As to whether Amazon would care where you bought books previously, unless they have a monopoly on the book what could they do. And why would they want to. Most retailers do not try to punish you for buying elsewhere. They do not refuse you service or even give you a dirty look if you walk in wearing or carrying items bought at a competitor.

An interesting question, but Amazon focuses more on giving good service rather than spying on customers at present.
