I also no longer have notification noises on, I just have a thing on my wrist that vibrates. Again, a not insignificant quality of life improvement.
If I used iOS instead of Android I'd probably have an Apple Watch instead of a PT, since that works better with that platform.
I don't really care about smart watches being a platform for apps. Maybe that has stalled, but it doesn't matter to me. I haven't found a single app for the PT I think is useful. It doesn't mean I don't find my PT useful. If I lost it today, I'd order another one without hesitation.
