But the Kindle doesn’t run either, I think you mean the fire tablets and not the e-readers?

[trevcanhuman]

Yep. This is for [e]Kindles. It's a screen reader that uses e-ink screens that save a lot of power and barely have any of that blue light that hurts your eyes.

It's just grey-scale colors.

Completely different from Fire Amazon tablets.

You're right I'm thinking of the Fire tablets. Allegedly if you jailbreak your Kindle you can manage your library and collections with Calibre.

[Semaphor]

You can manage your collection with Calibre (and at least used to auto-strip DRM in the process) without jailbreaking, I did that with the Kindle Keyboard many years ago.

The only thing I remember about jailbreaking, was being able to use custom screensavers and fonts.

[QuikAccount]

I don't think you can strip DRM any more. At least I can't with my Kindle Paperwhite and Calibre.

[joecool1029]

You can still, but unless the libraries needed to do it are updated you'd need to use the last version of Calibre built on python2.

I didn't have any issues removing drm from my purchased amazon books as of a few months ago using the latest version of calibre released at the time and the latest version of the kindle for windows app.
