A friend of mine got a G watch and was nice enough to sync my phone to it and let me use it for a couple of hours. I was impressed with it and will get one, although I will wait for the Moto X as the G watch and Gear Live are too ugly.
It was too short of a time for me to really get a sense of how it is to live with it, but the functionality of it was really good for me. I have a pretty busy work schedule with a lot of meetings and heavy email volume. I'm normally pulling out my phone to check for my next meeting, or to see if the email I just got is important, and being able to quickly glance at my wrist instead was awesome. I also use Google Now for a lot of stuff, so seeing the cards on my wrist was pretty cool.
My take is that Android Wear is awesome if you have a busy schedule, get tons of emails, and/or use Google Now a lot. If one or more of those does not apply to you, Android Wear isn't going to be very useful for you. When I get one I'll probably just wear it at work, then in the evening and on weekends switch to one of my regular watches, as my personal life isn't so busy that I need to check my phone constantly.
As for charging... I have automatic watches that I have to stick into a winder every time I take them off (unless I know I'm wearing the same one again the next day, which I usually don't). Putting a smartwatch into a cradle isn't going to be a big deal for me.
