> but after 6 years with a Garmin Fenix still holding 90% of its battery (and being able to replace it), I'm not their potential customer.
What kind of battery life did you have when you bought it, and how long is it now?
Does Garmin still upgrade the firmware?
Garmin doesn't really upgrade the firmware after the next model release.
But you'd be a fool to believe a hardware startup would do so anyway.
I have a 7S and it still gets updates regularly.
