Sure, you can buy a Windows PC for fewer up-front dollars. But the true cost of ownership should be calculated based on not only the acquisition cost, but the residual value after you sell it or trade in. It’s the difference between those two numbers that really tells you what your computer costs to own. When you calculate the cost of ownership in that way, Macs win easily. All you have to do is compare the value of a Windows PC from, say, three years ago (which is often close to zero), and compare that to what you can get for your 3-year-old Mac. It’s virtually always no contest.
