Microsoft dominates the personal computing world, with Windows found on 90 percent of computers worldwide and Office or Works found on nearly all computers that require a word processing suite.
Apple, on the other hand, completely dominates the MP3 player market with the iPod, the tablet market with the iPad and a decent chunk of the smartphone market, with the iPhone.
In April, Apple reported that revenue jumped to $13.50 billion, thanks to strong Mac computer and iPhone sales.
