Ubuntu
“ Ubuntu is a community developed, Linux-based operating system that is perfect for laptops, desktops and servers. Whether you use it at home, at school or at work Ubuntu contains all the applications you'll ever need, from word processing and email applications, to web server software and programming tools. Ubuntu is and always will be free of charge. You do not pay any licensing fees. You can download, use and share Ubuntu with your friends, family, school or business for absolutely nothing. Ubuntu is an African word meaning “Humanity to others”, or “I am what I am because of who we all are”. The Ubuntu distribution brings the spirit of Ubuntu to the software world. ”
I'm switching to Ubuntu. It is very nice. Obviously it takes a bit of learning but there are lots of people ready to help, plenty of forums, tutorials and books. I'd rather know what I'm doing then just click buttons that do things in mysterious ways.
