I'm running Windows 10 in bootcamp on my 2015 Macbook Pro , and found out today my employer participates in the Microsoft at home program which lets employees purchase MS Office at a steeply discounted price. I can get it the Mac or Windows version for the same price. I'm mostly getting it for Excel as I have to use it for monthly expense reports, but I also have some other purposes for it. I'm looking at getting Visio ( vs Omnigraffle ) too, but that isn't included in the Office versions I can get. I think I read that Visio is only available on Windows. The way I see the pros and cons Windows version: all the features. Integrates with Visio if I get it. Not convenient since I need to run Parallels * VM or boot into Windows to use it. Parallels makes my cooling fans go into turbo mode. * Mac version: Convenient, no turbo cooling fan noise. Missing features. No Visio integration with Visio if I get it. Thoughts?
