wonder why people don't use Linux OS?

The most popular Linux computer operating system is Ubuntu, and all software is completely free. Well in this definition you don't have to pay, but you will need to spend time learning.

I have the oldest PC that could no longer run on windows XP (junked up and I did all the clean jobs). So installed Ubuntu.

I like it better than Windows for many reasons. Guess most people are brain washed by Bill Gates, or no sense of adventure. Ubuntu has the greatest forum in the world where you can find all things to solve any problems you may have.

At bottom of post, a graph of what OS the 3000+ people used when reading this blog.

Also note for windows users XP is still much more popular than Vista.
