Now it's officially the fastest-selling tech device in history. According to Bernstein Research financial analyst Colin McGranahan, the iPad has now sold an estimate 8.5 million units and is a "runaway success of unprecedented proportion." In an article in Information Week, writer Paul McDougall also notes that the iPad is starting to have a measurable effect on PC sales. A recent research study by NPD found that 13% of iPad users would have purchased a PC if they hadn't been able to buy an iPad.
Coupled with the recent start of iPad sales at U.S. mega-retailers Target and Walmart, the device is sure to break many more records over the holiday buying season.
