My work takes me in and out of busy offices all day long. I see Macs, I see PCs, I see servers and printers. I see PCs running Windows which is no surprise, but what I never see are PCs running Linux. “Why is this?” I always ask myself. I mean, the benefits of open source far outweigh the risks and from an administrative viewpoint, the OS is a lot easier to manage. So what is it that is holding Linux back? It’s not spreadsheets and documents –word files and excel files can be easily handled in LibreOffice– nor is it Access/database related as you can get KEXI running in no time. No, I will tell you what is holding Linux back and the answer is simple. Outlook.
