I came from a bb z10, i had no big complaints with the z10 other than the 1800mah battery. Getting work done the z10 had the hub with all the messages in one place and the swiping on screen was efficient. Now i have the lg watch and I can quickly preview my messages once they come in and see who is calling and decide if I need to answer right away. I don't have to constantly pull my phone out to see if the message is urgent, when I get a call I need to answer I don't even need to take the phone out, I just swipe on the watch and talk on my bluetooth. That way my battery is about 40% at the end of the day cause the screen isn't on constantly just looking at messages. My LG G3 is a beast and I couldn't ask for much more.
