DELL-

Generating about 60% of its sales from desktop and notebook PCs, Dell faces intense competition in the consolidating market it shares with Hewlett-Packard, Acer, and Lenovo. The company built its fortune with the "Wintel" platform (Microsoft's Windows operating systems, Intel microprocessors) as its foundation, and while that combination remains its bread and butter, Dell also offers chips from AMD and a version of Linux as options on some of its PCs. The company's PC sales are following an industry trend that favors mobile computers; Dell's notebook line, its largest revenue generator, accounted for almost a third of its sales in fiscal 2009. The company also made additional efforts to spur sales with high-end devices. Dell's gaming and multimedia PC offerings include its XPS and Alienware lines. It debuted a luxury laptop called Adamo in 2009.
