For me, the addition of satelite SOS introduced on iPhone 14 is a game changer. I do enough out of cell range activity that I carry a SPOT device.
The ability for one more device (and pricy subscription) to be eaten by my phone is fantastic.
For others it might be onboard ai capabilities.
Each incremental hardware update to an iPhone tips the utility scales for someone, and is a completely ignorable change for others. Some people don’t care a bit that the new iPhone has a 2k nit brightness, for others, that is the feature they’ve been waiting for to upgrade.
I don’t pay attention to androids much, but it is pretty rare for iPhone full number bumps not to have a hardware feature that is new.
This is not a replacement for a SPOT device. It's a backup. You might need to move around reportedly, point it very carefully to find a satellite, coverage isn't great, even minimal tree cover is a problem, etc. Plenty of cases where a SPOT device would be a life saver and where this would not.
I too would like to ditch mine. But I'd rather be alive in a real emergency than die because I broke my leg and can't walk around in a circle pointing the phone right.
