As a non-Mac-user, I've always had the impression (from Apple and the general public) that Macs are consumer-oriented devices (or at least non-corporate machines). The only significant impact they've had in business in my view is for creative professionals like yourself, and only because for a while Adobe tools worked better on Mac (which may or may not be the case anymore).

Schools used Macs because they were cheap (for the schools). Creatives used Macs because the tools were better. 99% of the other Mac users used Macs because it was more consumer friendly than the business-oriented Windows. Apple has never been in the business of catering to business.
