I'm sporting the Huawei Watch 2 Classic as I type. Still putting it thru it's paces - I got it for the NFC chip, but have to see if it's really worth it over the Moto 360 Sport (which I lost, but could have replaced for half the price of this). I also wanted to see if GPS would be a little better. Still testing.
Androidwear 2.0 is a definite upgrade. Still a real chore to manage/navigate, but it's a big deal downloading stuff directly from the Play Store on the watch....or with Wear Manager apps I'm unable to find I've had success opening in the Store on the watch (from my phone). FINALLY you can keep apps you don't want on your watch from installing from your phone.
But Play Music is still borked. It is THE most complicated, unintuitive, backasswards way I've ever dealt with trying to get music on a device.
And 4GB of storage is such a joke. First off, after the operating system you have more like 2.2GB. But then your watch won't actually let you use the last 500MB (explain this to me?!?), so you're down to 1.7GB. By the time you get done with the bare minimum of apps, you have about 1GB for music.
