Hall effect has been the norm in all but the cheapest sim gear (sticks, throttles, etc) for a very long time now.
Hall effect gimbals on radio control/drone controllers have been pretty common for some time, too.
It’s mostly that this is a solved problem that more general purpose controllers are just now catching up to after the problem’s been exacerbated by the smaller gimbals used in modern controllers.
That’s a really great point and another reason I’ve really enjoyed the Garmin experience – Garmin doesn’t try to sell your own data back to you.
Getting anything more than the absolute most basic of real time data out of a Fitbit requires an annual subscription. With Garmin, it’s just there.
