People like me buy Apples products, and investors that focus on Steve's health miss much of the equation. The degree that he actually affects future sales is in dispute, and investors vote with their $$$. Steve is obviously in for rough times, and I wish him the best. I have health issues too. The guy on the street that wants the new iPod or Macbook does not ask "how is Steve." People buy the product, and investors bet on the people that might buy the product.
