I agree that YOU don't need it.
YOU don't understand the real difference (along with many others). You think it's just a time-saver of 2 seconds from pulling out your phone from your pocket. This just shows that you don't really understand how the watch is worth it. Sure, I wish it was cheaper, but for the $350 Apple Watch Sport, it was worth it to me. It's NOT worth $700-$1000 to me, but to some people it might be.
I'm not going to try to convince someone that the watch is for them, because it's really not possible. Because people are all different. Some people have their phone out all the time, constantly fiddling with Facebook, twitter, emails, using it like a GameBoy, surfing the web, etc. - for those people, the watch will not help at all.
For those people who want to STOP using their phone (like me), it's amazing. I don't treat my phone like a GameBoy, it's there for 'when I need it'. For those people, the watch is such an amazing device.
