I Would Like to Know How People Use Linux.

I have been a linux user for 12 or so years..I am just to cheap to have to pay for upgrades, virus and malware software. I am just amazed at the industry that is involve with the windows software. If everyone as as cheap as me the economy would even be worst. All the business different business involved keeping your windows Pc running. I started out with Red Hat , the went to Mandrake..Now I am using Ubuntu. and I can do darn near everything everyone else can do. But in the 12 years I have been on linux I have never had a virus, or malware, or worms.. I can open those scary emails because they bugs they put in the emails can't read linux. so I am wondering how many people use linux and what distro are you using. thank you
