Manufacturers that use Google prefer using their own set up over stock Android and Google could concentrate on the one thing they have complete control over in their Google Services. Whether the person choose Apple, Windows, Blackberry, Samsung etc they will still have an option to the suite of Google Play Apps and Services despite what the UI look like.
For those of us who like to root and tinker this could be a nightmare but as much as I love Android I wonder if it is going to get to a point where Google fade from Android being the center to it becoming just a side project again with the main focus shifting elsewhere?
Unlike Android, their suite of apps and services can be marketed to the competitor. Blackberry has already caved and Windows is now looking to the Android Market. And despite how vast the iTunes App store is Google has made its presence more, so much so Apple is rethinking its strategy on keeping their apps exclusive.
Thoughts?
