What has Julie Green done that qualifies her for such a high position in the company? 



Things like lead the Windows 8 project, perhaps? She's the right choice. It's great to see women at the top. Beyond this, they are both very capable and proven leaders. Julie comes from a development background and has done an outstanding job in her what-was-current-yesterday role. She'll be a great engineering leader. Tami will rock the business side of things.

We're all surprised, too, but things happen. Welcome change Smiley
