Aesthetically pleasing designs also help to build a strong brand sense by influencing the most important human sensory organ, the eyes and consequently extending users' emotional attachment to the device (Vincent, 2005; Lindstrom, 2005). Mobile phones in different colours and appliqués have provided users with personalized options of these devices and transformed them from a functional tool to a fashion accessory (Research and Markets, 2005; Nokia, 2005; see Figure 2).
