We are using Debian for not only mail, web and DNS but also file, print and database servers. In addition, our many desktop clients and notebook computers are Debianaised. Windows systems are used only in VMware which is installed in Debian. We also sell Debian systems to many customers which amounts to more than 50 systems. Micorsoft Office and Adobe Photoshop, Illustrator are replaced by Openoffice.org and Gimp in our office. Our financial, operational and informational systems are actually working on Debian. Debian is powerful and is keeping the originality of Linux.
