I'm in the same boat. I got the LTE connected Apple watch and I absolutely LOVE it. I leave my phone AND my wallet at home pretty much everywhere I go now. If I get a phone call, or a text, I answer it with my watch.

I have phone, text, apple pay, music (spotify, pandora), maps, and so much more. Probably the only thing I miss is a browser to google something. But that's pretty rare that I need that.

The best part is that all of these apps work natively, without the phone nearby, entirely over LTE or WiFi.

Seriously if you hate carrying around a big phone, get an LTE connected Apple watch. It's a game changer.
