Why not use a browser based presentation app like Google Slides and not deal with stupid proprietary software that won't run on anything but a windows or mac machine?

Because Google Docs suck for any kind of actual professional work, instead of playing at office.

Exactly. Using non-portable formats when there are portable alternatives is simply stupid.

Surely, because Google Docs runs on my computer without any part of that closed source behind Google virtual walls.

If your the sort of person that's going to use bash on windows then Latex+beamer is a much better option than powerpoint.

Imagine: your presentations stored in plain text, in a human readable format that you can edit in your favorite editor, manipulate with a rich library of text editing tools and even version control. Powerpoint would be a silly proposition if that existed!

Funsies aside, Latex+beamer has a learning curve and so it is not suitable for the everyday user and thus Powerpoint has its market. But for the average HN reader it doesn't make sense. Take 20 minutes to learn Latex basics and thank me later.

Yes but does not work right now with office 2016 unless it changed recently.

What's wrong with office 2002?

Shutup and take my money
