I completely agree with this assessment. I got my Apple Watch SS on launch day but once the initial excitement wore off, I find I pretty much never use it for anything besides the notifications and main face. And sometime remote controlling my iPhone's music app (on a crowded commuter train, etc).
Actually, although I was initially excited about it, I found the Siri function to be utterly useless as it's much faster to pull my iPhone out of my pocket and do whatever I need to do than 1) snap wrist into view with enough force that the screen will wake up, 2) say "hey Siri" and wait for the Siri prompt to appear, 3) state command - for example, 'text my wife and tell her I'm on my way home' 4) wait for for the command to be understood (very hit-or-miss here, because if I'm using the Apple Watch, it usually means that the iPhone is in my pocket, where it gets horrible reception – meaning, Siri won't work half of the time) and 5) either press "Send" with my other hand, or repeat the entire thing from step one because it didn't work. They made it seem like you'd be able to eat you at least use some functions of the Apple Watch without having to use both hands, but I've never been able to do this.
tldr; it looks cool, but after using the Apple Watch for a year, I've found it to be pretty much useless for anything besides notifications and activity tracking.
