So what did it take for you to go to Linux?

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

VMs are what really did it for me. I was working at a health care job doing IT. Whenever someone wanted a new server I'd have to buy the hardware install the hardware load Windows server on it load the middleware on it, connect it to the SAN, add it to the complicated backup schedule. Literally anything anyone wanted took me a month.
I threw an ESXi box in connected it to the SAN once, worked out a mirroring backup solution. Now I could slice up one decent size box into dozens of smaller boxes. My real limitation was Windows licensing. Server and CALs and middleware gets pricey quickly. But I can install as much community-based open source as I want.
I started running Linux of the desktop to keep up with technology. Before long the vast majority of my servers were Linux.
