Like many people I know, I tend to keep my electronics for as long as possible, because (1) I always find that everything is too darn expensive — a trait I've inherited from my dad, I'm afraid —, and (2) I feel guilty whenever I have to replace them because there is no real way to know what sort of damages discarded electronics cause on the environment. So I still had my first Kindle, a 4th generation device from 2011, which I still loved, but lacked some features I really needed.
