Simple fact: Apple make the best and most profitable products in their categories. The iPod, the iPhone, the iPad and Macbook Air.<p>This strategy was probably chosen by Steve Jobs.
The 'best' part comes from the design team, under Jonathan Ive.
The 'most profitable' part comes from operations and sourcing, under Tim Cook.<p>They've nailed the mobile sector. They're starting to nail the computer market. People I know who have sworn by PCs for years are moving to Macs - why? They are the best designed laptops available, bar none. I'm holding Apple stock because they are the strongest company in a strong sector. Apple are going to take the profitable laptop market, the profitable music and video markets, and hang on to the profitable portable electronics markets. That's a massive market cap for them to usurp from Dell, Amazon, and Nokia/Samsung. Everyone else will be churning out cheap and cheerful low margin products.
