I was cleaning out some recently and I found an old Kindle E-Reader that I got many years ago as a present. A bit of research reveals that it’s a Kindle 4, so it’s 7-8 years old. However, the idea of an E-Reader with a no-glare screen seems like it should still work fine. This one still worked ok after I plugged it in, with the exception of the fact that the bottom 1/3 of the electronic paper display isn’t working. Is this something worth fixing? How hard/expensive would it be to do and is there still any support for this device if I do get it fixed?
