I am hoping for a surprise later this fall when Apple unveils the iPhone 6. Hopefully it will have a curved back so it's comfortable to hold. Apple turned away from the curved plastic back in the iPhone 3GS with the release of the iPhone 4. At that time Apple needed to release a phone with a new design. Other companies was gaining momentum with cheaper phones. It was harder for Apple to justify the high price of the iPhone when it was made of plastic. Most phones even today are made of plastic because of all the radio signals that need to pass the back of a phone. Apple replaced some of the glass back of the iPhone 4S with aluminum when they released the iPhone 5. The end result was an odd mix of glass and aluminum. The original iPhone had a aluminum top body and the bottom covered in plastic. It also had a curved back so it was comfortable to hold. Most people don't think Apple ever again will release a phone that is all or partly made of plastic. I never liked the design of the iPhone 4. It was a compromise between feel and usage. Apple understand this since all of their products has a curved back or curved edges except the iPhone. HTC has shown recently that it is possibly to release a phone with an aluminum body that has a curved back. My hope is that Apple once again this fall will prove that they are the leader in industrial design.
