I’m sure you don’t prepare business plans with charts and graphs. You don’t use online collaboration tools. You don’t schedule meetings for a group of directors.
I doubt if you would ever need to create business presentations with 100 slides.
You write your words down for blog posts, content articles, guest posts, short stories and maybe poems. So why do you pay for MS Office to do these simple writing tasks?
