I've abandoned all my pBooks purchased prior to the advent of eBooks (hundreds to the garbage).

I used to read MS eBooks, Adobe eBooks and Sony eBooks all now gone forever. When I read an eBook, I rarely go back to it. I move on. The only Books I have kept for generations are my Bibles. I own hundreds of them in English, Japanese and German. Plus, I own lots and lots of eBibles and references and electronic Bible devices.

If one does not have to strip DRM to read Amazon eBooks, then the stripping function is irrelevant. Plus, I have no reason to change fonts, metadata or anything else in my Amazon eBooks.

If Amazon goes out of business, I will deal with whatever corporation fills that vacuum and just forget all my Amazon eBooks.

Thus, Calibre will do nothing for me but expend labor which many may enjoy a lot. I spend lots of labor with all my mp3 songs and I enjoy that labor. Others may not. I have some songs recorded on the old wire recorders from the 1930's.

I use MediaMonkey to control all the data in my MP3 songs and that may be the way Calibre functions for eBooks. As some say, different strokes for different folks.
