“The feature is available in the United States after the U.S. Food and Drug Administration cleared it for sale, making the smartwatch the first consumer device to do so without requiring medical review.”

 Alivecore has the Kardia ECG that works very well and was approved by medical review. I imagine if one was truly concerned about their heart they would go with this device that is far more accurate, vastly less expensive, integrated with real-time medical review by doctors, or transmitted to you own. Even comes with a clip to fit to your smartphone. https://www.alivecor.com
They also support the iwatch.

 The watch probably isn’t accurate enough to pass medical review - thus the legal tie-up in other countries, not so much for the feature, but the ‘marketing’ aspect of it being a medical device. Neither are as good as an 8 point lead at a hospital - but can indicate something isn’t right with rhythm.

In Canada, after tax, Apple Care, and a case - you are looking at over $2000 for the new flagships. $1500 for the XR. 
This doesn't include the highest prices in the world for data plans ~$80/month ($91 after tax). 
Looking at around $4200 for 2 years of ownership. 

Apple is using the same strategy with investors as it did with the Battery Reporting in iOS 12 - give them a whole lot of useless data and sell the new narrative hard as ‘this is what’s really important’ - hoping nobody notices the 1 piece of data people really want, is gone. And the only persons with access to that data is Apple. 

Massive money grab meant to render out of warranty products useless. 
If the new iMacs and Mac pros have this, then Apple can kiss the Pro market goodbye. Who’s going to buy pro gear with no aftermarket value? Want to replace a HDD... that will be $960 at your authorized dealer thank you...

I’ve extensively used and reviewed all the main streaming music services... so I can actually speak from experience. 

Spotify is by far the best at curation, best GUI, ease of use, and connectivity. 
Tidal is by far the best sounding service with hifi streams and MQA - with the limited library they have.
Apple Music is the default pre-installed app. In the pack with Pandora, Last FM, Rdio, Google Play, Rhapsody etc... functional, but shines at nothing. 

Apple has the native integration on its devices (yet oddly enough Spotify Connect works better on them), so it’s no surprise that Apple is getting leverage from its platform in the US. 

The real question is, how many people on Windows or Android are installing AM? it’s negligible. 
Meaning that AM success is limited to Apple’s market share on it’s devices. 
While Apple is seeing remarkable success in the US of subscriptions on their platform - it is for now, quite limited in its growth potential. Although it’s a considerable market potential. 

Lets not forget that the concept of music Streaming Services is still in its infancy. 
Spotify is not limited to a single platform, and is overall a better platform - for now. 

I don’t see this industry having a clear winner one day with a total monopoly - it’s the last thing the music industry wants. Good for Apple, good for Spotify and all the others. A new industry is booming and people are finding a new appreciation for music. Everyone wins.
