“(…) functionality and design aren’t separate things. A large part of design includes understanding what needs people have and what technologies can be applied to solve those needs. Design also isn’t just about the user interface ‘skin’ of graphics, icons, and aesthetics that people see. It also includes the internal ‘skeleton’ of how the application is organized, the conceptual model and metaphors conveyed to end-users, as well as its functionality.” (Jason Hong ~ blog@CACM)
