PC shipments in the US dropped 2.1 percent in the fourth quarter of 2012, according to a new report from research firm Gartner. Despite the drop in overall shipments, Apple’s market share went up.

Apple’s fourth quarter 2012 market share was 12.3 percent, up 5.4 percent over the same period in 2011. HP (12.6%) and Lenovo (9.7%) were also up over 2011.

The big sucking sound in the PC industry is coming from Dell, down 16.5 percent, and Acer, down 21.6 percent over last year.

It’s also important to note that the data does not include the iPad. From Gartner:

Data includes desk-based PCs and mobile PCs, including mini-notebooks but not media tablets such as the iPad. Data is based on the shipments selling into channels.
