I also have the Lumina 920 and I agree with some of your points for sure. Good list of suggestions. One thing I think is weird is how the phone and Windows 8 desktop UX is a little different. Would be nice to be a little more consistent in things like how text selection is done, settings, live tiles, etc. The little things.

Microsoft needs to fork the Android free source code, and extend it to work with their proprietary and legacy software.

I cannot see Microsoft ever getting above 3% market share in the mobile market. Time for MS to join android, Mr. Ballmer.
