Gartner on Wednesday published a preliminary estimate for winter in sharp contrast to IDC's results that nonetheless shared a view that the iPad was shrinking PC sales, especially those of Acer. It saw Acer still holding on to third place in the US, but the system designer's share dropped 24.9 percent from year-to-year to put it at 11.3 percent of the US. Apple was at fifth place with 9.3 percent, but its market share grew a rapid 18.9 percent and made it the fastest-growing of the group.
