I had my coworker on her Mac Mini launch Excel for the first time after a boot and it took about 30 seconds. Yes faster than my HDD but much slower than launching Excel 365 in Windows 10 on a SSD. I thought SSDS were supposed to be allot faster for running MS Office apps. Besides Office 2016 on Windows blasts away the Mac version. I use Outlook and Excel everyday at work and they have many more features. I guess until I go SSD or get a new machine I will either be patient with Office or rather run iWorks apps instead which launch in seconds on my HDD.
