But, and take this as a compliment, Vagrant does change everything. I'm so happy with vagrant now I can really say I have the same OS as my server in my laptop, I can easily switch between them and distribute the env between my peers.
I agree, vagrant changes everything. At the moment, it is feasible for what we at work, yet. But I really want to use it more.
