The problem is that the watch is dependent on the phone for notifications. If the phone is off the watch will not get notifications for Gmail or Google Voice. I can setup the regular mail client but the I get the Primary, Social, and Updates Inbox from gmail instead of just the primary inbox. Google voice notifications do not come at all so i miss text messages to my google voice number which is my primary/public phone number. The workaround would be to port my number back to the carrier and use the carrier for SMS/Text messages.

ATT has number sync so calls to the watch and phone will hit each other, but it is not as smooth as you would hope and gets disconnected sometimes.

Battery life is much better using bluetooth than wifi or cell connection.

Just lots of little issues that are a pain to try to work around.

My goal was for me to have access to my important notifications but not have my phone "at hand" to tempt me.
