IDC painted an optimistic picture of traditional PCs in a Tuesday long-term estimate of their shipments. Researchers expected PC shipments to grow just five percent year-on-year in 2012, but pinned most of this sluggishness on the first half, as the iPad and other tablets were a "powerful distraction," IDC VP Bob O'Donnell said. However, a mix of the Windows 8 launch and ultrabooks was assumed to be creating "excitement" that would see a bounce back.
