The new fairphone 5 came out, it looks cool but the price is really, really high..
If it's a phone that can really last 10 years it could be good, but is that true? Is it worth it? I could get the one with /e/os from Murena because i want a degoogled phone with a bootloader locked, but is it usable on a daily basis?
That's not the question. There is no singular reason to buy the Fairphone 5 and a purchase is not necessarily a commitment to a full 8 - 10 years of use. Focusing solely on one aspect of the device, like its modular components or the long-term software support, is missing the bigger picture.
But it is the question.
OP wants to know if fairphone will last 10 years. The retort is that even if you can have a phone that is supported for 10 years, you won't want to use it that long.
Even if they use it for 5 years and then move to something else, it still offers benefits that very few modern phones have. And it's still the most ethical by an absolute mile. You don't need to use a Fairphone for the entire support period for it to become a worthwhile purchase.
