Curious, I've noticed that the iphones (as well as iphone 4) does not come in flip/clamshell types. Also, I am seeing less and less of them in regards to non-iphone types as well. I would imagine that flip/clamshells offers better protection to the buttons and screen, whereas, the iphones are a one-piece item and can easily get damaged. Why are the flip/clamshell models declining in popularity? Is it because having two LCD screens cuts on battery life? Or is it because the hinges eventually wears out and breaks apart due to overuse? Or is it something else entirely? Is Apple considering releasing a flip/clamshell model in the near future?
