then why have smart watch?

So if you don't have to charge every day it's not a smart watch?

It's not that difficult to produce a smart watch that can keep a battery for a week so I don't understand why you feel the need to condition people to get used to the horrible battery lives of popular watches as if it's the only way.

I'm a big fan of Garmin's hybrid watches that are smart "enough" but provide a 9 day battery life. Recently, Mobvoi made it possible to have an Android Wear smart watch with a multi-day battery (TicWatch). Something that Google Pixel will have you think to be impossible.

I actually did do garmin watch for 5 or 6 years before recently jumping to apple. In most ways I did like my garmin better.

My only day to day upgrade with apple watch, is it allowed me to stream music to my airpods on a run without my phone. But I think Garmin has since released phones that can store music..

I'm not using my apple watch to run "apps" past podcast/music/running tracking.
