Vision

We believe that we are on the face of the earth to make great products and that's not changing. We are constantly focusing on innovating. We believe in the simple, not the complex. We believe that we need to own and control the primary technologies behind the products that we make, and participate only in markets where we can make a significant contribution. We believe in saying no to thousands of projects, so that we can really focus on the few that are truly important and meaningful to us. We believe in deep collaboration and cross-pollination of our groups, which allow us to innovate in a way that others cannot. And frankly, we don't settle for anything less than excellence in every group in the company, and we have the self-honesty to admit when we're wrong and the courage to change.

Empathy for Customers/Users
We offer superior products that fill real needs and provide lasting value. We deal fairly with competitors and meet customers and vendors more than halfway. We are genuinely interested in solving customer problems, and we will not compromise our ethics or integrity in the name of profit.

As a corporate citizen, we wish to be an economic, intellectual, and social asset in communities where we operate.

Innovation/Vision
We built our company on innovation, providing products that were new and needed. We accept the risks inherent in following our vision, and work to develop leadership products that command the profit margins we strive for.
