I’m looking for an eReader that doesn’t lock me into a particular ecosystem or format. Ideally I came just copy files over to it and have them work.
Other than that, small physical dimensions and a backlight would be great!
It’s been years since I had one but in the market again and I’m not sure the current state of things. My old one was a Kobo and took files just fine.
Using a Kindle Basic for a few months and it’s pretty great. No issues with side loading via Calibre and it was only about $60. Ads on the cover are a bit ugly, but never seen any in the interface beyond the lock screen.
