Whereas that 3 year old Dell laptop and Samsung phone are humming along quite nicely?

FWIW I just replaced my 5 year old MacBook Air, but only because I wanted to. It was still working perfectly well - and is now my flatmate's main computer.

Until last month my wife was using an LG G2 (2013 flagship), and it was still going strong. What killed it? A broken screen due to being dropped, and we decided that it was probably time for an upgrade rather than repairing a 4 year old phone.
