Hi,
for those who have Kindle at home and don’t want to use Amazon’s Infrastructure I prepared this blog post which describes how to jailbreak your Kindle and install open-source software on it :)
After you are done you will:
- have KOReader installed
- be able to load epub books into the Kindle via email
- create epub books from browser tabs
Post here: Kindle Jailbreak
I believe that if you already have Kindle laying around it could be beneficial to use it without Amazon software instead of buying Kobo/another alternatives. Or course - don’t buy a brand new Kindle just to do the jailbreak, you can invest your money to a different company


Also, battery will last much longer. Nowadays I have a tolino, but back when I had a Kindle, I kept it offline. I had no need for internet access. I just added books via Calibre and USB cable every now and then.
I think newer Kindle firmware requires setting up with an Amazon account at least once before it can be used offline, though.
