As measured by market capitalization, the number of shares outstanding times the price per share. Apple is worth $623.52 billion on Monday. That's way ahead of Microsoft, Exxon Mobil, IBM, GE, and all others. It's a long way from Wozniak and Jobs making the Apple I (just a mother board, no casework) in a garage. A lot of that growth comes from Mackintoshes, Ipods, and Ipads, new products created by Steve Jobs.
With a few more guys like Steve Jobs doing new product development, and we could grow our way out of Great Depression 2.0.
