According to data collected by The NPD Group, a research firm that closely follows the retail industry, Apple’s 13-inch MacBook was the top-selling laptop and the 21.5-inch iMac was the top-selling desktop in the retail channels during the month of October.

Stephen Baker, analyst with The NPD Group, explained that because Apple has a limited number of computer models, it has an advantage over its Windows (s msft) counterparts. In addition, he noted that the introduction of new iMacs almost always results in increased in sales for the company. Apple also had two of the top three best-selling computers during October. According to the same research firm, Apple took in 48 percent of U.S. retail desktop revenue from Macs.

The iPhone is a good introduction for many to the world of Apple, and some of that is spilling into the company’s computer sales. That said, Windows is is the dominant computer operating system.
