but what's awesome about Google Android? Google Search provided by Google? Google Location Services API using data provided by Google? YouTube provided by Google? Google Play Store and its associated APIs provided by Google?
the main services talked about as being 'missing' from AOSP all seem to rely on Google in the backend. they open sourced the Android OS, not Google, inc.
Maybe 'awesome' was a bit too much. Let me be clear: I find absolutely nothing awesome about Android ^^
Just today I got to set up my sister's boyfriend's new Xperia Z1. The hardware seemed nice, everything else seemed absolutely horrible. All the shitty and redundant apps you can't even uninstall. Everywhere I looked there were some shitty options and other hidden complexities. They even had some Kaspersky security software installed -- truly the Windows of mobile.
I may often have a negative outlook on the future of Windows Phone, but you can take it out of my cold, dead hands.
As for AOSP, I remembered this article from Arstechnica: http://arstechnica.com/gadgets/2013/10/googles-iron-grip-on-android-controlling-open-source-by-any-means-necessary/
It mentions things like AOSP Search, which looks terrible, AOSP Music, Calendar, Keyboard and the AOSP seem significantly worse. E.g.: "As you can see, AOSP Search is still stuck in the days of Froyo (Android 2.2). Once Google had its closed source app up and running, it immediately abandoned the open source version."
