Apple designers once again have scored with innovative use of materials. iMac first became an industrial design icon in 1998 when it introduced use of striking translucent plastic. The new iMac takes a dramatically different turn, making use of glass and ultra-thin aluminum, creating a new level of classy look. It’s a clean and simple design. The translucent plastic models in funky colors drew attention to the box. The new look makes it clear that this is a functional product where attention is focused on the desktop interface.
