Tell ya what, it is a great ecosystem though with multiple devices from iPad, Macs, Apple TV, etc. My other family members all have iPhones, and with me having one, it makes it all work out better between us. And getting imessage on the computer, or iPad without having to grab my phone is great. And the watch, runs on the wifi, and I get my messages on it without having to be in range of my phone. The Galaxy watch wouldn't do that if I got too far out of range of the phone. This is bluetooth only watches.
That is what is so nice, it is hard to get away from Apples ecosystem with how uniform everything works with each other. When I switch to Android, I feel like I am missing something.
