The whole TCO of Mac vs PC aside, there are definitely costs associated for a PC person to switch to the Mac platform. What were YOUR costs? Here were mine: 1) Books (D. Pogue) - $60 2) Software (in general there is way, way less freeware and fewer choices when there is freeware for the Mac ) - $400 so far 3) Additional Hardware and gear (outside of the basic unit - laptop, desktop) - $110 Total switching costs outside of basic computing unit: $570. And now I'm good to go. NOTE: Some of these costs are ONE time costs (like books), and some of those are optional (I mean, you could pretty much learn what's in those books if you checked stuff out of the library or really googled).
