! have the 38mm Apple watch, and I think it's best use is for notifications. It also makes a handy remote control for when I am listening to Music and my phone is docked at the other end of the room. Contactless payments is handy as well.
It also makes a handy second screen, for apps that support it. For instance, when travelling, I can set my destination on my phone, start some music, listen to it on my bluetooth headphones, then stick the phone in my bag or pocket and go on my way without having to stop to look at the phone. I know when I need to change direction, because the watch will tap my wrist to tell me to look at it.
As for battery life, that's unimportant to me. I have to sleep myself, as does everyone. When I go to sleep, I just take the watch off and attached it's charging cable.
Don't get me wrong. I find it useful, but it hasn't changed my life and I would get along just fine without it. I didn't even buy it thinking it would be useful. I bought it because I had a couple of hundred pounds, and I wanted one.
That said, there are a couple of apps I find useful on it. One is Bus Checker. This (and it's associated iPhone app) connects to TFL and enables you to look up bus times on the watch, or Phone.
Would I use 3 or 4G connectivity on a watch? Probably not, to be honest. I already have the ability to make and receive calls via the watch thanks to iOS's Handoff system, and beyond the initial James Bond/Dick Tracy/Micheal Knight thrill of talking to your watch and having it answer, I haven't had a use for that facility.
