The Google Nexus 7 beat the iPad at Japanese retail stores during the holiday season, says research firm BCN. The group surveyed 2,400 electronics stores around the country in December, and found that the Nexus 7 accounted for 44.4 percent of the tablet market, while the iPad took home 40.1 percent. Tablets made by local companies, such as Sony, only accounted for 2 to 3 percent of sales.
