I don't use Office365 much, apart from maybe Outlook (which I have to, for some of my work). However, the other day I had to use PowerPoint in the browser for the first time (I use Linux, so no native app) and… it turns out it's completely and utterly broken? I mean, the document looked nothing like the presentation my coworker ended up giving (using the desktop application on Windows(?)). What I saw in the browser was that positions were off, font faces and sizes were inconsistent, etc. etc. It was wild. How do they even manage to sell that?
