My HTC One M7 is 4 years old now, and still works perfectly. Battery life is not awesome but still lasts a full day with light 4G usage. I don't get software updates anymore, but that isn't an issue for me. I know that when the battery dies for good, or if the display shatters, I probably won't have a way to repair it, and that is bad because I really don't need a new phone. Availability and cost of spare parts, and ease of repair should be major decision factors for people buying electronics. It already is the case for cars.
