well, I am getting used to it now, and can report that I am really pleased with it. Here are a few tips:
When using it as a phone get a Bluetooth earpiece with volume adjustment. Any back ground noise and you cannot hear the speaker in the phone, and the earpiece volume is initially low and needs turning up.
Follow the ‘how to’ videos here and load in watch faces from the Google+ forum, it’s easy once you know how.
If you are only going to use it as watch for a period of time put it on Plane mode, the battery lasts for ages.
Load System Search, and use the triple click to make the screen typing
Hope that is of use to people, but a word of warning, once you have a watch like this, ordinary watches seem so dull!
