Amazon kindle. It didnt let me plug it into my computer and upload books to use it without internet access. Everything needed sending through amazon. I should have expected this but it was so locked down and filled with ads to the point it was unusable. I attempted to jailbreak it and it bricked so i threw it away and went back to using calibre on my computer. I would really like an offline open source ebook reader.
If you can get one of the early Kobo ereaders, you can flash this Libre OS on it, that would be better.
Also, those early Kobo ereaders (glo, nia, mini and some other models) can support up to 32gb sdcard, that's a lot of books and out goes the need for cloud storage
i've been desperately trying to get my hands on one of those, but I live in a third country and import duties are a pain
I found a paper weight at Goodwill about 2 years ago, and haven't seen one ad, and I have an email address for it that I can mail any file format. I have not had any issues.. maybe because I was a late adopter?
Nah, I had the kindle keyboard and it was great. Still is, if I don't want to read with a backlight. My first one stopped working after at least a decade, and a couple months later I came across one in a thrift store for like 10 bucks and it still works great.
