Why do you love it? Can you share with me your point of view.
Absolutely. I love the instant Siri access without having to pull my phone out. As many of us with a 6 Plus know, the user experience is great, but having to take out the mammoth phone and put it back in one's pocket cam be a nuisance. Siri is really great, and in watchOS 2.0 she'll be even better.
I really like seeing my calendar at a glance, the weather at a glance, being able to dictate long messages through Siri without pulling my phone out. It's handy when I'm out and about in the garage/yard and a call comes in. I can quickly answer it without having to take my phone out. Notice the trend? It's about being less tethered to my phone, and being able to do things without my hands being tied up with a device in it. I really like the Maps aspect when walking around, too.
What else... I have a SkyBell on my front door, so when my doorbell rings it's nice to get that notification right on my Watch.
I also like being able to control my music from the Watch. Again, it's about freeing me from my huge phone which I take in and out of my pocket WAY too much.
And I haven't even touched on the fitness aspect. Doing workouts is so much more fun when you have goals set on the Watch.
Oh, and I really like actually having a watch on my wrist to... you know... tell the time.
Also, my wife also has one, and we send taps and sketches to each other throughout the day.
Does anyone *need* an Apple Watch? Probably not. But quite honestly that argument is so silly these days. I don't need 99% of the things I own. But do I enjoy the heck of of (most) of those things.
