A post at TUAW summarizes the results of a study that does a good job of showing the problem with organizations not getting Macs because they are “too expensive.” Here are two paragraphs from the post:
According to the survey, Macs were cheaper to troubleshoot and required fewer help desk calls; system configuration, user training, and servers/networks/printing were all cheaper for a Mac environment than a PC environment. Software licensing fees turned out to be nearly identical for both platforms.
The survey doesn’t factor in the costs of the Macs themselves; Macs do present a large up-front investment, especially compared to the budget-priced Dells you usually see populating most office cubicles. However, half of the survey respondents noted they switched to a Mac platform because of a lower total cost of ownership.
