Years ago I had an E85 compatible vehicle when that was how we were going to save the planet before hybrids came along. E85 was cheaper than unleaded, but after crunching the numbers it was always the exact same cost per mile. Considering there were almost no stations with E85 fuel available, it just never made sense to go far out of my way to pay the same.
My first flip phone was free when I signed up for service. Next one I got because it had that push to talk feature a bunch of my friends and coworkers had. Last one was just to upgrade the second one. Added a camera, an external display with caller ID and track info when playing MP3s. Then I got into the early smartphones. Pre iPhone, Windows CE stuff.
If I were looking today it would need to be rugged as hell since I drop shit all the time, and I bet there won’t be a lot of cases for it. Capable of hotspot. Still want a camera (the best camera is the one you have with you). And a decent button feel since texting is going to be a way bigger PITA
