“For every 100 iPad impressions, other tablets have 14.75,” Gabe Donnini, Chitika’s data solutions engineer, said today. “Eighty-seven percent of the tablet web traffic in North America is generated by iPad.”

Chitka’s been tracking this stuff for a while, and while the number’s down month over month (above 88 percent for November, to 87 percent for December), it shows that iPad owners continue to use their devices fundamentally differently than Android tablet owners do.
