9 years, and I'm exaggerating a bit for effect; it's actually five of them. (HP 11 G2 in 2013, bought because it was tiny and worked well. Replaced with a Toshiba something, because it had a better screen and was faster. Replaced with a Chromebook Pixel 2015 because it was the god tier amazing Chromebook of your dreams. Replaced with an HP X2 because it was a convertible tablet and I wanted a convertible tablet. Replaced with a Pixel Slate because it was a faster and better-screened convertible tablet and I like things that are better.) None of them were replaced because I strictly speaking needed to replace them, and all got handed over to someone else who happily used them.
