for one.. have you looked at the stock price lately?
Compare it with Gateway or Dell?
Sure Mac is only 3-5% of computer market, but Apple is 100% of Mac production which means they make as many computers as most large computer makers like HP, Gateway, IBM or Sony... only Dell makes more units. Additionally, even though Apple product exhibit a significantly higher degree of production and materials quality, their profit margin is still highest in the industry. This is due to their basically monopolistic pricing power.
Apple's iPod and iTunes also is the 800lb Guerilla in the music download business. Everyone else is following...
QuickTime Mpeg4 is the industry standard for DV editors, Apple owns it.
Also, OS X is now the single biggest distribution of Unix. Unix IS the best, most robust professional grade OS available. Unix compared to Windows XP Pro is like Basic compared to Forth in the computer language world.
