I made the investment a year ago with AW3 Nike +. I am probably in around $500 to date between the watch, additional watch band, cover screen protector, etc.....
Its been a great investment on two points for me....I do 3.5 miles a day and it is far better managing my workout compared to my fitbit. It provides more relevant information in my exercise dashboard as well. I'm also able to control music now during my run without fiddling with my phone. I didn't spend the additional cash on the LTE version because using it kills your battery at an alarming rate and I don't want to spend another $15 per month with my cell carrier for a feature I will rarely use.
The other benefit involves Siri and my car. I am able to use Siri to voice control my cars stereo easier with having her on my wrist vs trying to yell at her on my phone that is sitting in a cup holder when fighting outside noise driving with the top down.
The new Apple Watch 4 is really health focused...here are the new features.......
electro-cardiogram feature (ECG)
fall detection - It will call an emergency contact if you do not confirm you are ok within 1 minute after a fall is detected
There's also a set of heart rate notifications, including one that's looking out of atrial fibrillation (AF)
Walkie-Talkie mode - Cool if you have a network of friends using Apple Watch
Larger capacity for more music
Podcasts now supported
larger screen by using more of the actual screen area compared to previous models
I can see the Apple Watch evolving into a true health monitor over the next 5 years which is great. Probably will also turn into a parenting monitor for us adults that have senior parents out of sight. The larger screen and safety focus makes it appealing for those that want to be more in touch with elderly parents that might need help.
