A few companies track PC shipments around the globe including iSuppli. In July, iSuppli offered up the numbers for Q1 2010 and Acer overtook Dell for the second place in the global PC shipment list.
The numbers for Q2 are out and Dell has recaptured that second spot. Dell shipped 10.5 million PCs for 12.8% of the market. Acer shipped 10.1 million PCs for 12.4% of the market. Acer had negative 6.2% growth for the quarter while Dell had negative 1.2% growth thanks to its desktop and server shipments.
