I am keenly aware that I benefit from a wonderful tradition in the UK of designing and making.

We struggle with the right words to describe the design process at Apple. But it is very much about designing and prototyping and making.

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.

It is sad that so many designers don't know how to make. CAD software can make a bad design look palatable! It is sad that four years can be spent on a 3D design course without making anything! People who are great at designing and making have a great advantage.

When I am in my painting, I'm not aware of what I'm doing.

I am the farthest thing from a computer genius.
