Tim Cook, chief executive officer of Apple Inc., holds an iPad mini during an event in San Jose, California, on Oct. 23. Apple said that the 7.9-inch iPad mini will cost $329 to $659, depending on memory and wireless features. With that starting price, the company is sticking to its strategy of charging a premium to preserve industry-leading margins in a market that NPD DisplaySearch predicts will more than double to $162 billion in five years.
