Yes Linux is better in the sense that it's more stable, it doesn't require a registry, not to mention it's free, and uses far less space, however there aren't as many programs that work on Windows that are available and work well with Linux, but they have their own programs.Everyone(including me) should put the time in and learn to use Linux. It is free and open source, which stops money going to Apple or Microsoft. Using a computer shouldn't cost anything.
I used to dual boot Linux Ubuntu and Fedora with Windows 7 back in the day.
You can even run Windows within Linux, i used to do this with Virtualbox.
