Got a very old kindle for free, from someone getting rid of it. No touch, no backlight, most basic thing ever. I only got my account on it to download a dictionary.
I am never buying anything from Amazon to read on it, but I've been using it quite a bit, only on calibre converted stuff. It was not too hard to set up, and once it's done it's just drag n drop.
Well, good luck to Amazon trying to wipe my kindle remotely with black magic then.
It doesn't have WiFi configured at all.
