I have very large hands and I stopped using iPhones after I first used the original Galaxy Note. I simply couldn't go back to the tiny screen even though i did prefer iOS. I went through a couple of large phones after this and never had a complaint. I bought an iPhone 6+ day one simply because it's the phone i had been waiting for.
Phablets may not be for everyone, but neither are the small phones that are rapidly becoming an endangered species.
