Why linux better than Windows?

Linux is being used everywhere. Especially where the main objective is to do programming. What are the reasons of its popularity?

• Forget About Viruses : Linux hardly has any viruses. And that's not like "Oh well, not very often, you know". That's like "If you've ever heard of a real Linux virus, please tell me". Of course, a Linux virus is not impossible to get. However, Linux makes it very hard for this to happen. Reason is simple that most people use Microsoft Windows, and pirates want to do as much damage as possible. Linux uses 'Smart Authorization Management'. In Windows you (and any program you install) usually have the right to do pretty much anything to the system.
• Drivers are not needed.
• Linux protects our system. Windows let trojans, adwares, spywares and viruses enter easily.
• Linux is free. It is an "Open Source Software" and the most common is the GPL (General Public License). This license states that anyone is allowed to copy the software, see the source code, modify it, and redistribute it as long as it remains licensed with the GPL.
