About the Linux platform
If you are running most of your data in the cloud, and all you really need is a solid web browser and a few local tools to work with standard document formats, then Linux will work well for you. Linux for the desktop has arrived. Linux works very well for file servers, because it's very simple and solid, as well as being open source, which means there are no licensing issues. You can run as many users on as many machines as you want, and the sofware is free. DSI supports Ubuntu Linux and advocates open source technology solutions.
