Design is not just what it looks like and feels like. Design is how it works.

There are really two things that have to occur in order for a new technology to be affordable to the mass market. One is you need economies of scale. The other is you need to iterate on the design. You need to go through a few versions.

Boeing just took $20 billion and 10 years to improve the efficiency of their planes by 10 percent. That's pretty lame. I have a design in mind for a vertical liftoff supersonic jet that would be a really big improvement.

I am saddened, not by Microsoft's success - I have no problem with their success. They've earned their success, for the most part. I have a problem with the fact that they just make really third-rate products.

I have always believed that technology should do the hard work - discovery, organization, communication - so users can do what makes them happiest: living and loving, not messing with annoying computers! That means making our products work together seamlessly.

The CEO of an aircraft company [Boeing] should know how to design aircraft, not spreadsheets.
