I used to be a Windows fan...
Advantages of Linux:
- Reliable (my machine has a 225 day uptime...)
- You can do everything on Linux what you can on Windows
- Open source (If you can do coding, you can modify it as you see fit...

)
If you don't want to completely change than install Linux just for fun. As a second operating system. This is how I started. You need to get a good basis if you don't have any previous UNIX experience. Than you'll see the big picture...
