Apple has owned the tablet market with the iPad until the Android tablets started appearing. There have been 14.8 million iPads sold since its introduction last year, with a whopping 7.3 million of those occurring in the fourth quarter. While the iPad market share dropped from 96 percent to 75 percent, it's probably not a real drop. Market demand is just beginning, and sales of competitor devices are likely new customers to the tablet genre, and not taking sales from Apple.
