pdfs don't have a hard-set text size, and cbr/cbz is just a bunch of jpegs in a rar or zip file, respectively. the first one is a non-issue if you reflow and the second one can be zoomed in to. granted, neither is ideal, but it's workable.

personally i've kept it to comics in pocket format.

My guess is that Amazon thinks everyone f9rgot about the Kindle Fire cuz that was before last quarter and that's as far back as they remember.

The remarkable 2 is apparently good for this if you know what you are doing.

I have one and I'm very happy with it, but I use it exclusively for todo lists and taking notes, so I have no need to tinker with it.

Onyx boox runs android. You could probably root it, but I've never looked into it

Pocketbook has always been the best option for linux because it already runs Linux out of the box and is easily modifiable by design

I also love my Kobo. I've heard you can unlock it and flash a community supported OS, which might be another true benefit over Kindle depending on your needs.

I recommend Boox, I don’t know about their dedicated e-reader, but I have the Onyx Boox Air C it’s a little pricier, but it’s an E-Ink tablet so I take all my notes there. (The C versions are color)

As someone who takes a lot of notes during their work, I can’t recommend enough. Gone are the days I’ve bought paper notebooks.

Did a quick google and the first review that came up shows that's not true at all, it's the exact same process on a kindle as it is a Kobo, though you and this review are both really over-selling it:

Getting ebooks from other stores onto the device is also a hassle. You have to plug the e-reader into your computer and drag and drop files (though Calibre, the ebook management app, does make it a scootch easier). But that problem isn’t unique to Kobo. Amazon and Barnes & Noble also insist you sideload books.

The real reason seems to be that the Kobo is cheaper, honestly, don't see why the kindle is that much more

Kobo

Thanks for this. Was in the market for an e-reader and didn't really feel like jumping through Amazon bullshit

Amazon also bought up a comic distributor a while back which may make this easier to get the content I want.

I’ve never had issues emailing PDFs and epubs to my kindle address to read them.

I’ll need to check out kobu though, they have a color one that’s $100 cheaper.

I want to read comics but I also don't want to miss out on that feeling when you turn a page and are greeted with awesome two page spreads.

Unfortunately no tablet or e-reader can have this functionality.

I quite like my Kobo Libra Colour

Youre looking for an Onyx Boox tablet - a little pricey, but worth it for the un-enshitified tablet.
