Steve Jobs sold the idea that the computer, formerly just a business machine, is a tool for artists and dreamers. In doing so, he captured the imagination of the world.
He didn’t personally invent the computer, or (as ReadWriteWeb points out) anything; but he understood that if computers were to become integral to our lives, they needed to be more than commodity objects. Apple remains the only company that really successfully considers the emotional design of a product.
To put it another way, Steve Jobs humanized computers, and his legacy is that they are more emotionally accessible, they’re better designed, and they empower anyone who creates in a way that they might not otherwise have done. And he did it in a way that made a product launch feel like a life-changing event.
As Om Malik says, our Elvis is dead. He will be sorely missed.
