Yea, idk, I’m upgrading my phone after 3 years, and if this buyer comes through I’ll have paid $100 for that 3 years of use.
I think a lot of people treat the idea of upgrading often as the old become ewaste immediately or is just kept in a drawer. But selling my used gear while it still has value keeps my overall burden down and devices much cheaper. I upgraded to the Pro Max this year, and out of pocket after this sale I’m spending $350. If I had had the Pro Max before I’d probably be getting another $100 or so for my used device. I’ll do the same thing in 3 - 5 years depending on if/when I have an incentive to upgrade again.
Laptops and tablets are a different story since they don’t keep their value quite as well as iPhones do, and if I’m honest have a much smaller impact on my daily life.
Most of those older $300-400 Android phones are ewaste for the most part after 3-5 years. Higher-end everything is more valuable and generally lasts longer. $50 work boots vs $400 work boots.
Modern $300-400 phones however I think will last 5 years easily in terms of performance depending on your needs.
