It only took only day this week for new Microsoft CEO Satya Nadella to confirm what the technology press was saying – that former Skype CEO Tony Bates and former Great Plains executive Tami Reller, are leaving the company. People asked me this week why Reller is leaving and unless one of the parties decides to spell it out, we may never know. Bates' departure seems obvious. Reuters coverage said he was passed over for the CEO job. In a letter to Microsoft employees on March 1, Nadella wrote, "Tony Bates has decided this is the right time for him to look for his next opportunity."
