The annoying part is that you can end up missing on new features.
I look at the Zojirushi rice cooker that I bought in college - a hefty purchase at the time - the Jaguar of rice cookers at a time when I should have been buying the $10 Black and Decker rice cooker. It's still with me, over a decade later, through countless moves, a handful of girlfriend (who all had opinions on it, interestingly), and at least 1,000 bowls of rice cooked.
The battery that keeps the time died (I could replace it, but I'd have to take it apart and it's technically non-replaceable), but other than that it's working perfectly. The rice is as good as it ever has been.
My oh most first world of problems? A while ago Zojirushi released rice cookers also function as pressure cookers in the same device. I'd love to upgrade so I can quickly make stews in it, but I cannot possibly retire my old one just because it's old.
Most likely I'm going to end up having two Zojirushis because well, rice goes pretty well with stew and you can't exactly make both simultaneously. And then in 10 years when they make one that's both a rice cooker, a pressure cooker, and an air fryer; I'll be having this monologue again.
