I'm happy with the size of my iPhone 5. Any bigger and it would be too much to handle comfortably, especially since I use the Otterbox Defender case to protect it. I can understand someone who doesn't a tablet or computer wanting a large phone if that is their only or main device. I can also understand wanting one if you carry it around in a purse, bag, briefcase. But since I wear my on a belt holster or put it in a pocket, a huge phone is out of the question. Besides, these things cost a small fortune and I've only had my iPhone 5 for about 13 months. I can upgrade whenever I want to, but I think it is a waste of my money to upgrade more than once every two years. As a matter of fact, I like my iPhone 5 so much I probably won't upgrade for a few more years, or whenever they stop supporting it, whichever come first.
