I have been using Microsoft Office on Windows for a long time, from 97 to 2013, and occasionally I use it on a Mac computer as well. There has been previous questions about comparisons between Windows and Mac OS, and I think this is one comparison between the two platforms that might be easier to test in terms of usability (although there are obvious constraints due to it being a product originally designed for Windows). I would like to know if there are any studies done on this, or if there are some ideas about the key differences in terms of usability and benefits/downsides when used in each of the platforms.
