Microsoft’s Macintosh Business Unit (MacBU) today announced a new Office v.X ad campaign that focuses on cross-platform compatibility and how Office v.X helps Macs and PCs to communicate. The ads, which launch nationally on October 12 in Mac, business, technology and design publications, portray an iMac and a PC as human personas spending time together in different environments (click ‘continued’ to view two of the new ads).
