Bought my Kindle when I retired in 2010. Keeps chuggin' along. It's even been to China and back now. Good thing they didn't check it; it's got a bunch of Bibles and history titles that might not sit well with them. Lots of third-party free stuff too, old novels, historical books, and such. That stuff I have backed up on my old Mac too in case of a whoopsie. Since my wife commandeered the Kindle, I mostly read my e-books on this iPad.
The file system on a Kindle is pretty simple. I've blown mine out and reloaded from the Mac a couple of times. Amazing what will fit in a couple of gigs
