VirtualBox is a free, open source, cross-platform application for creating, managing and running Virtual Machines (VMs).
You've heard a lot about Linux and you'd love to try it out, but you don't know enough to take the plunge and install it alongside Windows -- maybe you're worried you'll wipe all your files off in the process. Besides, you'd like to have another computer handy so that you can look something up if you get stuck, but you don't have another computer. This is it.
Or maybe it's the opposite. Perhaps you've taken a step out of your comfort zone and ditched Windows -- maybe for Ubuntu, or maybe for Mac OS X. You feel liberated! No more Blue Screens of Death! You're living life on the edge, getting on with your work… and then you come to a screeching halt. You discover that a piece of software crucial to your workflow runs on Windows… and only Windows.
Whatever shall you do? Then somebody introduces you to VirtualBox. Suddenly you gain the power to conjure virtual computers out of thin air. They don't take up space on your desk, yet they work just like a real computer does. They can be conjured up and removed with little more than a few clicks. Intrigued?
