My wife got this for my birthday/Christmas. I am quite enjoying it so far. There's a Lollipop update that is supposed to be out to all watches today, but mine has yet to get it. I've kept my eye on the android wear stuff for a while but it was the round face of the Moto that was its biggest attraction to me.
I have yet to use it a full day but I am already seeing how it will change my life. It's nice to be able to look at the time, weather, google now notifications, IMs, hangouts, email, and who is calling all from my wrist. I am not into the fitness stuff, but I guess it's nice to know it's there.
The two big things for me are the integration with GPS navigation and music. I use those two things quite often in my car (98% of the time my music is being streamed from my phone). I never cared to buy a dock for my phone, I just generally sit it next to my gearshift. Since I drive with my left hand at 12 o'clock most of the time, I can just glance at my wrist for the nav or do a quick tap to pause or navigate songs.
More playing will happen over the next few days and more apps will be installed and uitilized, but so far I'm a happy camper.
