*Unless you are providing maintenance on a charge per call basis

**I still prefer Linux as you can be certain that the OS has been configured correctly, there will be no OS upgrades that will break the installation & there is (almost)no risk that the IT Dept. will insist on installing additional software that interferes with its operation.

Stuck in a never ending cycle of file copying.
