I'm thinking of getting a Series 3, because the hardware improvements (bigger screen, increase in performance, ECG) just aren't worth the difference in costs to me. Am I wrong? All the comparison reviews I've seen say I'm wrong.
I've also been waiting for an Apple Watch with enough battery life to use for sleep tracking. That's something I WANT to pay a steep premium for. Any chance this will happen with Series 5? Is it worth the wait to find out?
