For sure, the Apple Watch is effectively a miniature iPhone, but I’ve not yet been in situations where I’ve missed this connectivity.No LTE. No Siri. No text messaging. No email replies. Poor music implementation. Inferior audio quality. Limited app integration (e.g., airline QR codes). Limited availability of Garmin Pay vs Apple Pay. No unlocking Macs. No unlocking phones when wearing masks.
Don't get me wrong, the Epix is a great sports watch (and better looking that an AW IMHO). And I rely on Garmin to train for and run multiple marathons each year. But the AW smartwatch capabilities are extensive, which is why so many runners I know continue to wear both.
The Epix does offer notifications when your phone is near, which I do like getting while at work, but I’m not using Garmin Pay or on-watch music, as I prefer to run listening to my own self doubting inner voice.
