Here is an extensive recent study , complete with time budgets, that shows the advantage means big bucks in for-profit operations. That is just one item in a long list of reasons which compell any rational person to choose Mac over Wintel. Those are what most companies want to sell you. Only Apple sells Macs. People also fail to consider total cost of ownership, opting for the lowest initial outlay instead.
Initial prices are now quite close.
We get a great many more problem calls about Wintel, and the latter problems are harder to fix. Steve Jobs was one of the 2 founders of Apple. I'd rather be rich like him than rich like that Bill guy. Linux is gaining huge popularity because it is free and more malleable and reliable than Windoze. FreeBSD is another good one to consider.
