Well, I didn't want to be TOO rude ;-) I realise that there are a lot of huge companies that have tied themselves into Windows. I'm just pointing out that the trend I've observed, at least here in the U.K., is for new companies (which will one day become the behemoths) to use a variety of clients, either running cross-platform apps or webapps. Our company went from a mac shop to a chromebook one practically overnight. There might still be some barriers there, for some companies, but far less so today than 10 years ago.
