Amazon.com has given Brian Valentine, who was head of Windows Vista development until he resigned recently, stock incentives worth more than $12-million at the current share price. The stock award was filed with the Securities and Exchange Commission (SEC) and gives Valentine 400,000 shares which will vest between September 2008 and September 2012 at a rate of 20 percent annually as long as he's with the company. Before he resigned, Microsoft said Valentine, a 19-year veteran, would be reassigned as soon as Vista shipped, and the unit handed over to senior vice president, Jon DeVaan.
