PC sales won't grow as much as expected for 2011 in the wake of tablets like the iPad, Gartner said on Wednesday. Originally expecting the field to grow by 10.5 percent, it lowered the mark to 9.3 percent and a total of 385 million computers. The analyst group blamed it chiefly on the collapse of netbooks following the iPad's release. Tablets like Apple's weren't necessarily replacing all notebooks, but they often led people to stall getting a new portable PC.
