Linux is an alternative operating system you can use it on both PC's and Apple Macs instead of Windows or MacOS. Or as well as.

It's free, and comes with loads of free programs. It's stable, you don't get blue screens of death, it doesn't suffer from viruses and these days it's even quite easy to install! You can leave it running days, weeks, months even years without ever having to restart it.

Some commercial games even have secret linux versions or their CD roms.

I am browsing this site using a browser called Konqueror and a desktop system called KDE which completely stuffs Windows in the eye-candy department and NEVER crashes!

If anyone is fortunate enough to have an Athlon-64 computer you may even find that Linux will run 2-3 times as fast.

Anyway, let me know if you want advice and I will point you in the right direction!
