I guess I'm in the 4" is perfect camp.
I use my devices one handed all the time. I'd like to think I'm an average guy with average hands. My GS2 was a stretch, my GS3 is a pain. I love the phone, dont get me wrong, but it gets dropped frequently.
When I went shopping for a new device for my business line, I was certain it was going to be the Note 2. I had a 4s on it, until 4 months ago when I had to swap to my old BB Bold to be allowed on the corp network for a contract I was on (daughter got the 4s).
When I got to the store, I started playing with phones, and left with the 5. Ive always been an iOS fan. I forgot how nice it was to use a phone that fit in my hand.
To each their own, but it works perfect for me.
