Apple has become the biggest buyer of semiconductors in 2011, according to the latest data by market researcher Gartner. It pushed ahead of Samsung Electronics and HP. In 2012, Apple spent a total of US $17.3 billion in sourcing semiconductors as raw material in making its products. Gartner attributes Apples growth to solid sales of its iPhone and iPad brands, and the success of Macbook Air, which became a path-breaking product as it pretty-much defined the requisites of what go into making performance ultra-portable notebooks such as Intel's Ultrabook specification. Apple's semiconductor purchases grew from US $12.8 billion in 2010 to $17.3 billion in 2011, a 35 percent growth. At the second place is Samsung, with $16.7 billion in semiconductor purchases, a 9.2% growth.
