Office 2011, which gives Mac users the same collaboration and social networking tools that shipped with Office 2010 for Windows, offers a direct connection to Office Web Apps, which is Microsoft's cloud-based version of the desktop suite. From Web Apps, users, whether on a Mac or PC, can store and access desktop-created documents from any location with an Internet connection. Web Apps also provides co-authoring tools for people to work on Word documents or PowerPoint presentations together, provided they are using either Office 2010 or 2011.
