Apple
Computers are still an important part of its mix, but these days music-related products are at the top of Apple's playlist. The company scored a runaway hit with its digital music players (iPod) and online music store (iTunes). Apple's desktop and laptop computers -- all of which feature its OS X operating system -- include its Mac mini, iMac, and MacBook for the consumer and education markets, and more powerful Power Mac and MacBook Pro for high-end consumers and professionals involved in design and publishing. Other products include servers (Xserve), wireless networking equipment (Airport), and publishing and multimedia software. The company's FileMaker subsidiary makes database software.
