Quotations

The more I learnt about this cheeky — almost rebellious — company, the more it appealed to me, as it unapologetically pointed to an alternative in a complacent and creatively bankrupt industry. Apple stood for something and had reason for being that wasn't just about making money.

Jonathan Ive, in iconeye 004 (July/August 2003)

Good design is also an act of communication between the designer and the user, except that all the communication has to come about by the appearance of the device itself. The device must explain itself.

Donald Norman, The Design of Everyday Things, Introduction to the 2002 Edition

In their work, designers often become expert with the device they are designing. Users are often expert at the task they are trying to perform with the device. [...] Innocence lost is not easily regained. The designer simply cannot predict the problems people will have, the misinterpretations that will arise, and the errors that will get made.

Donald Norman, The Design of Everyday Things (1988), Ch. 6
