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.

Only co-founder, CEO, and Apple crusader Steve Jobs may have expected the level of success the company's music-related products have enjoyed. In 2003 Apple announced the launch of an online music service called the iTunes Music Store that lets computer users purchase and download songs for 99 cents each. Apple has since expanded the offerings to include music videos, audiobooks, television shows, and other content. The store's catalog, which has helped spur sales of Apple's popular iPod digital music and video players, includes songs from the five largest record labels, as well as television content from ABC, NBC, and a number of cable networks. The company has launched international versions of its iTunes Music Store that serve Canada and European Union countries. Early in 2006 it began offering select television content on a subscription basis with a service called Multi-Pass. Later that year the company launched an online movie service, and previewed a device called iTV for watching downloaded content on televisions. Apple announced availability of its television device, redubbed Apple TV, early the following year.

Dell

Whether you spend most of your time in a cubicle or on a couch, chances are good that there's a Dell in front of you. The world's #1 direct-sale computer vendor provides a broad range of computer and entertainment products for the consumer and enterprise markets. In addition to a full line of desktop and notebook PCs, Dell offers network servers, workstations, storage systems, printers, LCD and plasma televisions, projectors, and Ethernet switches. The company also markets third-party software and peripherals. Dell's growing services unit provides systems integration, support, and training.

Entrepreneurial wunderkind Michael Dell pioneered the direct-sales model for computers and took the company from his dorm room to the top of the PC heap by keeping it focused on a simple formula: Eliminate the middleman and sell for less. Dell's built-to-order boxes allow for lower inventories, lower costs, and higher profit margins -- elements that leave it well armed for the PC price wars and IT spending recessions.
