I agree, it has obvious advantages but in my case I give higher priority to aesthetics.
And that is why choice of sizes is a good thing. One size doesn't fit all and it never did regardless of how much Apple wanted people to believe it did.

This is Apple. Specs don't matter, remember? Hardware/software blah, blah, blah... tight integration... blah, blah, blah... software optimization, etc.
It seems specs don't matter around here when it doesn't affect you. The moment it does, seems like spec chasing isn't the sole provenance of Android. Get the 4.7" phone and be happy. You will have a phone that is more advanced than any iPhone you have or can get today. It will take you 2-4 years into the future with nary a worry. That 4.7" phone will likely meet your every expectation, and most likely surpass it.
Like penis envy, it's an unnecessary worry that you can't do much about.
Speaking of Renzatic, where has he been? Does Samsung have him buried in work trying to get the inside scoop on the iPhone 6 and the iWatch??
Disclaimer: This post is intended to be humorous as Renzatic and I are MR buddies. But I don't work for Samsung.
Is that enough smilies? Or should I add a few more, just in case?
