Linux doesn't degrade with the time even if you install / uninstall a lot of software as Windows does
You can move the installed OS from machine to machine with little or none issues even with different chipsets/motherboards
When update your OS, you also update your apps.
You can use your hardware longer due to less system requirements
You can customize the system better
You can choose from different Desktop environments (Windows an Mac user don't know even what this means)
You can trust software more than "cool programs" downloaded from "a cool site"
You get features others try to achieve with 3rd party software with different success (compiz, multilevel clipboard, virtual desktops)
You easily can run services on your workstation to act as a server an vice versa
If you don't like a particular Linux Distro, you can pick another one
You can develop your own distro (from scratch or based on someone's else)
