Apple is not showing signs of slowing down as it tops BusinessWeek's list of best corporate performers. If the 42 million iPods that were sold over the span of five years is not enough to convince you that Apple deserves the top spot, maybe the 216% increase in profits in 2005 might just make believers out of you. Investors are bullish about the company now and more so in the future as they see Apple dominating digital entertainment.

But while the iPods are making the headlines, the Mac has brought in 39% in total Apple sales in 2005. Analysts believe that the iPods will continue its growth, but the Mac will play an increasingly important role in the Apple's future growth, after all, the PC market is way bigger than the digital music. With Apple getting only 5% of the $75 billion home PC market, there's just too much room for growth and Apple will surely want a bigger slice of the PC market pie.
