Linux Phones

iPhones already have the longest software update cycle on the market (though many manufacturers are finally catching up), this could make a 7 year phone become a 15 year phone nowadays since the annual hardware changes are kinda meaningless. That's ridiculous, in a good way. Of course it's been possible for the many Android devices that support PostmarketOS for quite a while, but then those are phones that had way less original support and much smaller market share individually, so if this catches on, it could be even more impactful than Postmarket on Android phones.
