Lol, we are already using the non-Google version of Android OS. When the devs makes their custom ROMs they come with 2 builds. One is called Gapps (google's apps & service included) and the other one is called Vanila (not even a shread of Google included here). We even have to manually install camera app here. Yeah some of the apps doesn't work in the vanila build since they are google service dependent but the phone itself isn't useless. We can use the rest of the things as usual.
