Apple led the worldwide media tablet market in shipments, with nearly 4.2 million units shipped in Q3 2010. The iPad grabbed 87.4 percent media tablet market share worldwide.
IDC defines a media tablet as a device with color displays larger than 5 inches and smaller than 14 inches, running lightweight operating systems (such as Apple's iOS and Google's Android OS) and powered by either x86 or ARM processors. On the other hand, tablet PCs run full PC operating systems (Microsoft's Windows or Apple's Mac OS) and are based on x86 processors.
A previous report from two months ago said that the iPad had 95.5 percent of the market. Apple says it is not worried about the competition. In fact, Tim Cook, the company's COO, recently downplayed Windows and Android tablet options.
