Former Apple designer Don Norman believes that Apple iPhones have lost touch with well-designed iPhones. He says that important designs often have small and low-contrasting text that makes it hard to read. He also thinks that the iPhones are not suitable to be used without a manual, and thus making the designs inefficient and inconvenient. He says that the iPhones break every design sin and that everything involving using the iPhone has to be memorized.
He criticizes the iPhone for not being accessible enough for people that lack the dexterity and vision of an average person. Design could be enhanced to be easier to use for everyone. This is interesting to think about, especially given the popularity of the iPhone.
