Fairphone promises height years of upgrades (apparently thanks to a contract with Qualcomm which sucks less), compared to the usual 2 or 3 years max in the Android land.

So it's cost per year is probably smaller than other devices if you manage to keep it this long. It being repairable probably helps.

(I don't have a Fairphone, but if I had to buy an (Android) smartphone, I would seriously consider the Fairphone)
