THIS.
I lost so much work in the 90s and 00s. I was a kid, so I had patience and it didn't cost me any money. I can't imagine people losing actual work presentations or projects.
Every piece of software was like this. It was either the app crashing or Windows crashing. I lost Flash projects, websites, PHP code.
Sometimes software would write a blank buffer to file too, so you needed copies.
Version control was one of my favorite discoveries. I clung to SVN for the few years after I found it.
My final major loss was when Open Office on Ubuntu deleted my 30 page undergrad biochem thesis I'd spent a month on. I've never used it since.
