Samsung is planning a major 60 percent spike in its notebook shipments in a bid to overtake Apple in the worldwide notebook arena, part suppliers said Monday. It had shipped 10 million portables in 2010 but hoped to move 16 million to 17 million this year. Both companies were nearly tied through the first nine months of 2010 and saw Apple move just 150,000 more systems, according to Digitimes' IDC numbers, or enough that Samsung was within striking distance.
