The barometer is for the phone to get a faster GPS lock. Not for atmospheric pressure for weather applications.
Phone isn't LTE, so personally no go for me being on an LTE network.
Also, I've had LG phones before...no thanks. Nuff said.
Wireless charging is something I would like to use, though.
By the time my contract is up in another year, they'll have 2GHz quads with 3GB of ram. I'll wait till then.
