@63johnwYes all done and working.
It took quite a while to install as an update and then I factory reset to see the out of the box experience.
The battery drain issues from the preview versions has gone.
The Nokia Apps are all ending, Lumia camera, Mix Music, Here Maps etc...
Windows Camera is basically the Lumia camera without the name, you can still install Lenses etc...
No replacement for Mix music that I've found so far, a shame, I really liked that!
Here Maps has been absorbed by Windows Maps and you can still download Maps for any country for free!
I have found an Alpha version app for Hangouts called "client for hangouts", so I might set the phone up later as my daily driver and see how I get on?
How are you finding it John?
