> If you buy a used phone every year from someone buying a new phone every year, it means that you both use one phone every two years, right? It's a lot worse than buying a new phone and keeping it for 8 years.

Because when someone says "buy used" they're obviously telling you to buy the antiques your grandma used to love back in the day on an annual basis. Anything newer than that especially from the last year or two would be new and insane to consider, especially if you keep it more than a year. You really owned me with the flawless argument there.

I don't understand what you say, but you sound like you did not like my question.

I was merely pointing out that "buying used" is not necessarily better than "buying new but keeping for 8 years". Many people "buy used" but often.
