I remember a friend talking about load balancers when they were first came on the market 20 years ago. Cisco had this thing called "localdirector" which I believe couldn't handle load in the first place, while competitors did load balancing in hardware.

I was puzzled why people bought them.

My friend said, "Look, people buy $1M of cisco equipment, and they can just add a line item for one or 10 of these with no friction"

So, I think Apple made their watch a "line item". People buy a phone, and they need cables and the watch is sitting there, and they say "ok!" and try one.

(aside, I love my garmin watch. I just put it on my wrist. I haven't hooked it to my phone or connected it to the internet. It is great with battery life. I track my sleep, which seems to be when most people put their apple watch on a charger. I put my watch on the charger during my shower, which is all it needs)
