Ever since the release of Linux there has been a debate as to if it is better than Windows and why. Most Linux fans will have a long list of the things the operation system can do better than Windows.
Security is one of the biggest concerns with any computer and Linux shines in this area. Since it is an open source code there are more users able to help track down any issues and resolve them quickly. With guarded code only authorized programmers can see problems and that takes longer to fix things.
Linux is designed to be much more reliable as well. Certain critical system functions do not get glitched by other faulty software that has been installed. Meaning that where Windows would want to shut down or crash, Linux is set up to stay running smooth and just shut down the offending program.
The support for questions you might have with Linux is amazing. Being that it is a community of world wide programmers all you need to do is access their forums and an army of people with knowledge of the system will jump to help. Which is a huge difference from the support at Windows.
