I went directly from Office 2004 to Office 2011 for Mac, without going through the box in 2008, many criticized for lack of VBA. Office 2011 is homogeneous with the Windows version, and perfectly compatible with it, with a limited number of points of superiority and inferiority. The Mac version of PowerPoint works (finally!) Perfectly. Word is fully realized, but, depending on the computer equipment of the recipients of your documents, they will be or not be able to read them if you do not take the precaution to save them in an earlier version (.doc) unless they have their side downloaded application Open XML Converter.app allowing them to open your document. Excel has at least one bug, although minor annoying: you can not change the font size of the headings of rows and columns. The negative is the poverty of Microsoft support service. If you experience difficulty, you are good for nerts crisis ... 'and despair.
