Microsoft released Office for Mac before there was even a Windows version. Over 10 years before Keynote even launched. Office v. X released the same year as OS X, two years before Keynote and 4 years before Pages. Keynote was made because Steve Jobs wanted better presentation software than what others provided that was more like Concurrence on NeXTSTEP.
