What really amazes me is to hear people say that they have issues with Windows, especially Win7. I have run every build of windows since before Win3, all of them heavily used in a technical business situation. I have also run Macs for quite a while and taken care of Linux networks. I have never found Win to be any more troublesome or difficult to administer than any of the alternatives. I have no problems with crashing or viruses. I have no doubt, based on what I've heard, that others do have issues. My point is that it's certainly possible to have an efficient, trouble free system based on windows.
