I've still not joined the smartphone bandwagon - initially I couldn't justify one on the basis of price, then in the intervening years I've acquired netbooks, MP3 players, cameras and GPS units, so I don't really have a use case for one now.
My current phone is an 8 year old Samsung Ch@t 335 inherited from my wife, and it does more than I need as it is, plus the battery (original) still lasts 10 days between charges. I might eventually get something I can install LineageOS/Copperhead/Replicant on, if I really have to.
