Welcome back
I really do not wish to leave... It's been so long that it's just ingrained into me.
There are things I wish I could change about iOS, many are novel or more convenient, but I've built my daily life on apps, iOS and hardware combined.
That and the fact the if I went android, it would be a nexus phone. Samsung introducing S-Voice, and S-Cloud etc. just rubs me the wrong way...
And yet, the Notification Center, split keyboard, and opening apps from the lock screen don't bother you? Interesting.
