Also saying Kobo. I’ve got the Kobo Libra Colour and love it.
It’s the only ereader I’ve ever owned but I used the spouse’s Nook and Kindle a couple of times in the past and the Kobo kills it. Granted, we’re talking about a nearly new release of the Kobo vs a 5+ year old Kindle so it’s not a fair comparison.
Because of eInk and auto-sleep, the battery lasts me well over a month of casual reading (~30min before bed) with the occasional multi hour weekend session. Backlight is present and is totally readable in dark areas at <10% brightness; 100% brightness is like a supernova in your face. While the Libra Colour is not specifically a note-taking tablet like a reMarkable, it does just fine for quick notes/todo lists/etc but I did splurge on the ($60) stylus. There’s a “notes” application that comes pre-installed.
eBook support for writing in margins (or over text), underline/circling, highlighting, etc is really nice but occasionally the highlight is flakey when trying to highlight the end of a paragraph. That seems to have been specific to certain epubs rather than an “always” thing, but it happens in around 20% of epubs I’ve used.
EDIT: Notes and highlights you do in an epub (and presumably other formats) are exportable to your PC via Calibre (“Annotations”). I love this because I like to highlight things I find interesting, particularly good quotes, and this gives me an easy way extract them while retaining a reference to which book it was and where exactly in the book it was. Example attached.






Bonus points for no jailbreak required : D I didn’t even realize there was a jailbreak for it (or what benefits there are to jailbreaking it… I should do some research but I haven’t found anything I couldn’t do with the stock firmware and it sounds like you generally came to the same conclusion).
Mine is using the stock firmware, wifi off unless using Overdrive, but I plug it into my computer to charge and load it with books. It just shows up as a mass storage device like a USB thumb drive and you can copy/paste books onto it (or use Calibre). After disconnecting it will scan for new/changed files and auto-import any recognized formats into the reader application.
