In my area of work, I need an operating system that allows me to use my computers hardware to its fullest potential. This is why I use Ubuntu. I have been using linux for the past eight years and have never ceased to be amazed at the monumental increase of performance over OS’s such as Windows Microsoft. Ubuntu is under constant development and continues to be the fastest, cleanest, securest and user friendly Operating System out there. Best of all, its free.
