iOS's smoothness is great. When you're using a touch interface, having it be as smooth as possible is great. Yes, yes, function matters. No one is saying it doesn't. But form matters a lot, too. Also, transition animations can really bring a phone to life. They're visual indicators of what an app is doing. Taking a photo with a camera and having the snapped shot visually move to the lower right thumbnail is genius. Visual cues help people learn the OS. They're important. iOS 7 has a ton of visual depth. I love it.
I'm surprised Samsung locked the Note 3 down. What's the benefit? Only to appease carriers. I thought they had enough clout to not stand for that nonsense anymore. They made a ton of carrier variant models with the GS1 and stopped doing that nonsense with the S3 (2?) onwards. Why start it up again now?
