Powerpoint is what made me originally vow to try to never use word or powerpoint again, about 15 years ago. I was making a mathematically-dense presentation and became so frustrated with it that I wanted to throw my computer out the window. I still was somewhat new to latex at the time but figured there had to be some way to make presentations in latex. Found beamer and have never used pp for a real presentation again.
As someone that grades undergraduates, I’m happy that they not use the letter “x” to imply multiplication.
