I think that the base premise is faulty here. I use shell (fish, specifically), git and sublime text every day. However, I use them for specific purposes.

If you want to show people what's so good about git, put them in situation where renaming files won't cut it. If the task they have at hand can be effectively solved with renaming files and emailing them, then they don't really need git. Another example: excel. It's an excellent tool for data analysis, especially on the first stage; on my bioinformatics course, it was the first, and by far, the most useful tool I've been taught.
