I was first introduced to Vagrant at my current company - where my manager had prepared a VM + set of Chef recipes for setting up and managing VM hosting our app.
I had spent few days later setting up few VM's for my personal projects - I must say that having easily deployable VM's, each one serving specific purposes, all on my laptop, using just one base box (CentOS in my case) is a really a time saver - especially when dealing with projects utilising multiple technologies. But what is most important is the fact, that all those technologies are not polluting the main machine and creating misc combinations of them is as easy as branching / cloning my Chef + Librarian + Knife repo.
