Including the iPad, Apple is the leader in mobile PC sales.

A report states that if the iPad is counted as a PC, then Apple is the largest mobile PC vendor in the world.

DisplaySearch has released some research that shows Q4 2010 mobile PC shipments by vendor, units sold and market share percentage. Apple ranked number one with 10.2 million units and a 17.2% share, HP ranked second with 9.3 million units and a 15.6% share. Finishing the top five was Acer, Dell and Toshiba.

Apple previously announced during its 1Q financial call that they had record Mac and iPad sales. Maybe OS X 11 will make the iPad a true PC.
