iPhone is 'enormously underpriced': Warren Buffett
World's third richest person Warren Buffett, while celebrating his 88th birthday on Thursday, said that the iPhone is "enormously underpriced" despite its $1,000 price tag, owing to its utility. "I have a plane that costs...a million dollars a year. If I used the iPhone like all my friends do, I would rather give up the plane," he added.
