Apple is biggest buyer of semiconductors, Gartner says

Apple became the biggest buyer of semiconductors last year, ahead of Samsung Electronics and Hewlett-Packard, Gartner said on Tuesday. Apple's increased semiconductor spending is the result of a number of factors. The company sold more smartphones, and its tablet business was also highly successful in 2011, according to Gartner. The success of the MacBook Air also increased Apple's semiconductor demand, it said.
