Were you on crack.

The main reason why i got rid of the GS3 in general is because im not to fond of Samsungs skin that they have over the Android OS. I rather have a pure android experience. And with that, it takes ages for other manufactures and carriers to push out android updates. Sooner or later, they wont push out a update for it at all when the phone is old news. Had experienced that with Motorola and i didn't want to go back. Sure its a great device, but id pick Windows over Android for a more unique and enjoyable user experience. Just personal preferences.

There's alternate launchers you can use plus ROMs and the XDA community does a fair job of keeping phones updated.
But you could have got a nexus, regardless of your service provider they get updates from Google.

I just cant back Windows Phone after having used one for over a year. Its a painfully over simplified OS and it gets old and boring fast.

The Nokia Lumia 920 is pretty good, not as complex in my opinion (its a windows phone)
