Cyanogen user on n4 for a long time because I don't want g' bits and bytes on my cellphone I find this unsettling. I see the following points on it (I would refrain from calling them plus or cons).

-The reason I did the change is avoid G using MY device as their personal Wifi scanning station, the switch meant battery 2-3x more, I hope Microsoft doesn't mess with Android that way.

-If they roll it for all devices I hope they keep a version without it, or an extra package to install like g apps.

-Nice to see Microsoft being so flexible and going on so many fronts, the more they diversify the better, if this makes Android better; Android users win.

-Could this be the start of Microsoft Android?.

-Does "deep integration" offer any kind of advantage?.
