I've been working with contractors designing and building a house on a nonstop basis since I learned about all these systems of audio, construction, electricity, energy, water systems.
I knew a lot about product design before coming to Apple, but I didn't understand a lot about consumer experience design, which is really Apple's forte.
If you don't have an emotionally engaging design for a device, no one will care about it.
Nest really came out of a process where I was trying to design the most connected and the most green home that I knew of. I was curious of just about everything that goes into a home and building a home.
I say homes are for families, and you have to make sure you design for the family, not just one person: kids, your wife, your grandparents need to be able to use it.
I've learnt something from every failure. The products I helped design at the first two companies I worked for were utter failures. But now I know why.
When I encounter a problem - something that's not quite right with a product - I enjoy breaking it down in my mind and exploring possible alternative solutions: Why this? Why not that? I apply the latest in technology and design to reinvent that product and solve my frustrations.
Over the next ten years, everything that has a cord is going to have data in it.
