I'm thinking of buying S4 and I've been fooling into this sub-suite for a few weeks and I'm not sure.
I have an Iphone and airpods and I love them so I'm well integrated into the ecosystem. Only I use Spotify, and I heard it's not great on Apple Watch. So I'm skeptical about that part.
I'm not someone who goes to the gym or starts, and I do other sports where I can't wear the watch.
The Apple watch seems great, and I love Apple, but it's pretty expensive.
Hope to see good answers!
