Not only in USA, in Spain too.

Thanks a lot for that URL!

People who want a headphone jack […] are unfortunately a very tiny minority of the entire population.

People interested in paying more for fair trade materials and repairable phones are also a very tiny minority of the entire population.
Of course I don’t have any statistic, but I would guess that the proportion of people wanting a Jack is significantly higher in the group of people interested in buying Fairphone that on the general population.

In my particular case, I’m still using my Fairphone 3, and I’m not buying a Fairphone again unless it has a Jack.

Absolutely not, of course it is about having fun.
Are you going to just experience something that makes you feel miserable? Not an unfun moment for catharsis later, but an entire make-you-feel-awful experience?
Getting lost in a fantasy world is about having fun.
