OTOH, watching the presentation this morning, not a lot of new appeal for Apple Watch 4 over my current Garmin Fenix. So we'll see.
As a tech person, I always found the Apple watch to be more on the 'smart watch / techie' side of things - and more aesthetically pleasing.
There is no doubt that the Garmin does a better job of actually recording a ride, or transmitting heart rate to your cycling computer, or just about anything activity-based. So I was always swapping my Apple for my Garmin before rides, workouts, etc.
I always knew there was a shortcoming with even the Garmin when it came to heart rate accuracy - it just didn't respond quickly enough to sudden changes in heart rate (ie. going up a hill at full throttle, etc) - so I tried a heart rate strap on the chest. The Garmin heart rate strap for the chest is perfectly accurate and responds to changes in heart rate immediately. I have that paired with my cycling computer on my bike...and I no longer swap watches depending on what I'm doing.
I've learned to appreciate the Apple Watch for what it is - a device to record activities where heart rate accuracy isn't necessarily 100% important - such as a quick training jog or a quick treadmill workout at the gym, etc.
In either event, I've rambled long enough. I'll be first in line for the new Apple Watch 4 - and will sell my Apple Watch 3 shortly after. I might keep my old wrist strap though. :D
All of the features the AW provides beyond the 935 are implemented poorly. Any noise from street or wind or water made the AW phone features useless. For texting, only bareable responding with a few words or less. Siri did not work.
With the 935 I gained battery life, big screen size, better fitness tracking, sleep tracking, and still operates with wet (rain or sweat or swimming) fingers.
Even if I get notified of something on my AW, couldn’t do anything about it without my phone.
Sometimes I missed carrying a phone on long distance runs for the camera. Eg. Moose!
I’d like a smaller phone like my old Motorola Razer for my runs.
