after extensive photography testing for a week, few points below:
1. Noise level with Pureview is really impressive, not the usual marketing BS. ISO50 option rocks.
2. The Gallery is a step backward from N8
3. Bokeh for portrait is nice, dslr like softness. Can trick your friends that it was taken using dslr prime lense
4. Blank screen bug sometime using the camera button, apparently fixed in next SW Update
5. Pureview automatic and scenes mode generally create better picture compared to creative. Most probably my skill that need to be sharpened

6. Camera battery consumption is good.
7. Video recording and rich sound recording is noticeably better than iphone 4S, N8 and G3. Sound capturing is so good that it can be a minus point when there is wind blowing nearby.
8. Few defaults that need to be tweaked before using - Jpg quality to high (60% to 90%) and turn on video stabilization
9. Using Sport mode for higher shutter speed works well for moving subjects.
That' all for now my observation, compiling my Flickr gallery now and share later. Next up will be honing my Creative mode and experiment more combination of settings
