I have a pretty clear recollection of having heard about VCS in an undergraduate class, but presented in the most boring possible way, so I learned whatever I needed to regurgitate for the exam and moving one.
A few years later, I found myself working in the industry and using a real VCS (Microsoft's dont' recall the name), and realizing this was the same thing I have being doing lamely for the last two years with daily zip files and lots of notes on the README.txt for each project.
If you are writing hello-world, maybe you don't need a VCS. Anything bigger than that can benefit from using one.
