Chitika Insights (http://www.chitika.com) says their latest research shows that, based off of impressions across their network, the iPad accounted for 94.64% of all tablet based traffic. 

This is impressive in and of itself but to put this number into perspective, the next closest competitor, the Samsung Galaxy tablet, boasts a lack luster market share of 1.22%. Coming in last, in respect to traffic share, was the Barnes and Noble Nook with a meager 0.53% traffic share. In defense of the Nook, it is used primarily as an e-reader, with the capabilities of a tablet, according to Chitika, an online ad network and data analytics firm.

“Going forward the competition is going to be hard pressed to find a way to overthrow the seemingly omnipotent Apple,” says Chitika. “Not only do they offer a great product they have the undying devotion of their enthusiasts. Thus far Apple’s iPad offering has been able to thwart any attempt by competitors to develop a rival (or even equivalent product).  Apple produces a product that is both aesthetically pleasing and technologically robust.”
