PowerPoint for Designers
Microsoft's view of the Mac world is upside down. A huge proportion of corporate presentations are created by designers using Macs. But the Mac version of PowerPoint is a lame, tame, minimal version of what's available in Windows.
Microsoft would better serve their corporate user base if they created an industrial-strength version of PowerPoint for MacOS that could not only do all the operations of the Windows version, but surpass it. Custom table styles! 9 levels of text in text boxes! SuperTheme creation! Custom Effects Themes (Shape Styles)! Custom SmartArt! All of these are possible with the current file format, MS just has to build a program interface.
Rather than viewing the Mac platform as second-best based on market share, understand that is the platform of choice for designers who create corporate templates that make Windows more accessible and beautiful.
Of course, this would be a more expensive program, more comparable to InDesign than Outlook. But it could do so much to eliminate the common misperception of PowerPoint as a lame refuge of the elderly and infirm.
