Roz Ho, well known for her role in leading Microsoft's Macintosh Business Unit, is leaving the group after seven years to work in the company's Entertainment and Devices Division. Craig Eisler will be taking over the reigns as Mac BU general manager.

In a post on Microsoft's Mac Mojo blog, Mr. Eisler commented "Microsoft and Apple are both great companies in their own right, and working in Mac BU, I get to experience the best of both worlds. I am super excited to help Mac BU continue to rock the house with Office 2008 for Mac and beyond."

Mr. Eisler spent time as Microsoft's DirectX development manager, then left the company to take on the roll of CEO at Action Engine, and later form AOL Wireless. He rejoined Microsoft in February 2007.
