RVM for Windows: vertiginous's pik at master - GitHub

Using a virtual dev environment (with vagrant) seems like a good move if you're stuck on windows. You get to develop with software that runs on linux using whatever tools you're comfortable with on windows.

I only briefly looked through the README, but why is this necessary? Does The Real RVM (tm) not work (well) on Windows?

Is still Ruby and Rails slow as hell in Windows?
