The following is very much a rumor, but if true, it would be absolutely huge. A UK publication is reporting that Apple is considering buying ARM Holdings -- aka, the company behind most of the world's mobile phone processors. If Apple were to buy them, it would likely reshape the mobile landscape completely. To be clear, London's Evening Standard is only citing "gossips" within the city's financial district. But those gossips aren't the only ones convinced there is something to this talk: ARM's shares went up 8.1 points today, with more than 5 million shares changing hands by midday, the paper reports. The deal, would apparently see Apple buying ARM for something in the neighborhood of 5.2 billion British pounds, or roughly $8 billion in U.S. dollars.
