A new Microsoft SEC filing published late Thursday revealed that the company punished its CEO Steve Ballmer for his inability to turn around the company's struggling mobile efforts so far. The proxy statement notes that his total compensation of $1.35 million, including a $670,000 base salary and a matching bonus, was lower than in 2008 due to the "unsuccessful launch of the Kin" and "a loss of market share" for Windows Mobile. The Compensation Committee singled out the absence of a real Windows tablet rival through a need to "take advantage of new form factors."
