I was playing with my brothers iPhone 3GS the other day, and I was noticing that I liked holding it, I liked the way it felt in my hand, and It was easier to type with. I own a 4S, and I couldn't stand typing on it without a case on. Even my sisters iPod touch seemed too thin to hold and type comfortably without a case on it. My question is would you prefer the iPhone 5 be thinner, or would it be ok if it stayed the same thickness. My opinion is that it would be nice if it had a rounded back, and stayed as thick as it is now. What do you think?
