I am an MCSE and a Linux specialist. What people need to realize is that the nature of most businesses has little to do with Microsoft or Linux! Their products are merely tools we use to run our businesses. Migrating to Linux (particularly on the desktop) simply because we don't like Microsoft and its practices is not necessarily a sound business reason. If we choose to migrate to Linux, it will happen when we are convinced that it will make our users more productive and increase our profit margin.
