Alignment commands don’t work, so alignment has to be done manually.The equations don’t reflow with the text, so have to be manually placed.The bitmap screenshot is low resolution, so doesn’t print well.It’s hard to resize the text to match the equation picture, and visa versa.The fonts are unlikely to match up correctly.However this has it’s own problems, for instance: To avoid this problem, most scientists I’ve seen tend to copy screenshots from the LaTeX output of their papers, and paste them into PowerPoint. Although Microsoft Office equations have great keyboard support too, if you know where to look. The GUI approach takes a lot longer to enter equations compared to LaTeX (once you’ve learned LaTeX’s syntax).It’s a pain to have to re-enter all your equations again into a new tool.Whilst PowerPoint has an equation editor of its own, it is not a great match for LaTeX-using scientists, because:

There are many reasons for this, but one key one is that LaTeX provides great support for creating equations. However, for equation-heavy academic publishing, many scientists prefer LaTeX. So it’s not surprising that it’s a very popular tool-I see a lot of folks presenting PowerPoint presentations at machine learning talks that I attend. For creating presentations there’s a lot of features in PowerPoint that are hard to beat.
