I think the kindle books are still available if you login at the right url. They were for a bit, long enough for me to download them. It's difficult though. You're just fucked. I have like four kindles though and they work fine without an Amazon account. Never even need to turn the wifi on. Getting books on there with a USB cable is slightly annoying but not really. I don't know about any other product. I recommend avoiding all drm content for this reason. Luckily kindle books can have their drm easily removed. Not that I'd ever do that cause it's illegal. Lol.
