It looks like I'm not the only one not impressed with the iPhone 5, with Apple co-founder Steve Wozniak wishing that the new sixth-generation iPhone 5 wasn't just a taller, thinner, faster iPhone 4S. Wozniak says Apple were arrogant in their decision of keeping just a single 4-inch sized iPhone 5.

He notes that the Cupertino-based company should've created two sizes, a smaller iPhone, and a larger as well as wider iPhone. His chat with TechCentral gave quite a lot of insight, and opinion into the company he helped form:
Part of me wishes that Apple had not been so kind of arrogant and feeling we're the only one with the right clue. I wish they had made a small and a large version of the iPhone; that would have been great for me. Keep the aspect ratio the same, horizontal and vertical the same, but just grow it in the other way.
I think Apple tricked itself and said 'oh you could reach everything with one thumb' and I don't see anybody having any trouble using the larger screens. Apple said that as a defensive move because when the other phones came out they all had larger screens. Apple is now trying to run with that defence, saying 'we are right' and really there's a mix of people. Not all people want the same thing and a lot of people really like the big screens.
Apple really did push the whole 'one thumb' thing, but not every human being on this planet has the same sized hands. 20 million-plus are happy with the 4.8-inch Samsung Galaxy S III, and 10 million-plus are happy with the even bigger 5.3-inch Galaxy Note smartphone. Wozniak does agree that Apple hit the mark with the 9.7-inch screen on the iPad, though:
Here's where it bothers me. I walk into my phone stores: AT&T, Verizon, Sprint, and I see all these modern smartphones. Big, big, big, big, and there's the iPhone. If you compare the screen size right there in front of you, whether it means much or not, it may be fewer pixels, less information on the screen, but you get a feeling you're getting more with a larger screen.
And that talk doesn't apply to the iPad though. The iPad always had a great price for the size of the screen. Why would you want to buy the smaller screen devices? They looked a lot more like copies than any of the phones did.
