Once the PC leader heralded for its direct sale, build-to-order approach, Dell has since adopted a bigger retail focus and an outsourcing manufacturing plan that has not delivered on its turnaround promise. According to an IDC report cited by UBS, Dell lost more than a percentage point of its worldwide market share in the fourth quarter compared to the same period a year ago. Even worse, Dell's grip on its home market was even weaker. Dell's U.S. market share fell four percentage points to 22% in the most recent quarter. To help offset the decline in its PC stature, the firm has been pushing in new directions. Last year Dell made a $3.9 billion deal for Perot Systems to boost its IT services efforts.
