The geometry available and the frankly very subtly good alignment-snapping that it has makes it very useful. Posters, ERDs, I'm sure there are other applications too.
Eventually it's crass refusal to do anything even mildly useful taught me the exact set of eggshells to walk on to have a somewhat usable program but the damn thing just wouldn't work. I tried everything, including uninstalling and reinstalling the entire office suite. Nothing changed. My poster was not complicated and my laptop was school issued and more than capable of running a single PowerPoint slide.
I know this is a post of a man's passing. The PowerPoint he built worked. I remember PowerPoint as a usable and fun slide making tool that was usually the highlight of relatively tedious school projects. To see the bug ridden landfill of "BI" "features" it is now is sad. I genuinely spent a day trying to download an old version that wasn't running 3 "ai" processes in the background. It was a simply disgusting experience and i will never use it again.
