“Why aren’t Apple Macintosh computers more popular in large mainstream organizations?” asks PBS’ Robert Cringely. “I think Macs threaten the livelihood of IT staffs. If you recommend purchasing a computer that requires only half the support of the machine it is replacing, aren’t you putting your job in danger?… I am not claiming that every organization should throw out its PCs and replace them with Macs, but the numbers are pretty clear, and the fact that more Macs don’t make it into server racks has to be based on something, and I think that something is CIO self-interest. Macs reduce IT head count while Linux probably increases IT head count, simple as that.”
