So not only is it a far quicker way to make a PPT than using Powerpoint. I also see it used for making presentation videos, interactive PDFs and even animated GIFs/HTML5 animations.
The number of motion graphics marketing videos I see which are actually just Keynote files exported to video is impressive.
(Sadly, my work laptop is Windows. So I create them on my personal laptop then migrate to PPT and do my best to fix up the fonts on Windows.)
It looks so much better than the grid enforced by Excel.
I have a numbers file for my personal finances and it is so nice having some tables at the top with mortgage info and then details below. It makes running what-ifs super easy. Charts in excel and GSheets just kinda float over your content awkwardly.
Why would someone need to buy them, they only run on macOS and macOS hardware comes with it by default, doesn't it?
Not sure why tbh, my other invoices are done in LibreOffice.
The apps themselves are fine IMO.
