On February 26th, Kindle customers will lose the ability to download eBook purchases directly to their PC. If you want to switch to a rival eReader brand in the future, I suggest that you use the soon-to-be discontinued “Download and Transfer via USB” feature to archive your Kindle library.
I got a secondhand Kobo on eBay for less than $100, almost in new condition (the seller just forgot to include the charging cable, but luckily I had plenty of spare micro-USB cables). It’s a 2018 model, but it has 8 GB of storage, plenty for most people, and a nice 6" 300 PPI screen with warm light and dark mode. It’s more than sufficient.
Point being, alternatives are out there. reMarkable and Boox aren’t exactly equivalent devices, since those are meant as more e-ink note-taking tablets, not dedicated e-readers. You could probably find a 2018 Kobo Clara HD for around $40-50 used nowadays as well… and it has more features than the equivalent 2018 Kindle.
Yeah it seems I misunderstood what those tablets were,
I did find the old Samsung Tab tablets that would do pretty decent job though, those are somewhat around the same price range too, like 70-140ish range preowned
And looking into the kobo clara series it does look like those are about 120-130 second hand currently so not as bad
