I am very aware that I'm the product of growing up in England and the tradition of designing and making, of England industrialising first.

Unless we understand a certain material - metal or resin and plastic - understanding the processes that turn it from ore, for example - we can never develop and define form that's appropriate.

Deep in the culture of Apple is this sense and understanding of design, developing, and making. Form and the material and process - they are beautifully intertwined - completely connected.

One of the things that is particularly precious about working at Apple is that many of us on the design team have worked together for 15-plus years, and there's a wonderful thing about learning as a group. A fundamental part of that is making mistakes together.
