It's you. I know a street where just about every business uses only Macs. The fact that most of them are print services, graphic artists and architects may have something to do with it.
But I have seen the type of work these people do, and if you came in claiming some other OS is better, they would just laugh, and a few may give you the chance to show them you duplicating a job.
Sorry but you will look a fool, an OS without the right tools is of no use to someone who needs to make a living with the machine.
