Network World has declared Macs to be half as expensive to run as PCs.
Columnist Winn Schwartau said the associated costs of PC ownership make them more expensive. He cited antivirus protection, firewalls and IT staff as associated costs that add up to $1,300-$4,000 (about £750-£2,300) per machine per year.
"We included all of the third-party security products needed to keep a WinTel machine somewhat secure and checkbox-compliant," he explained.
Schwartau expects Apple to make some significant effort to expand its market. "Apple's non-iPod growth is going to need to come from displacing Microsoft's Vista as the de facto next-generation operating system for enterprise migration," he said.
"At recent security shows I have seen that more than 50 per cent of my compatriots use Macs and recognise that OS X was a huge leap forward. We are all suggesting some forms of migration. The small enterprise and home office should migrate completely, and some mid-size enterprises will take the plunge."
He also reports that large organisations he knows are deploying Macs, including sales and marketing teams.
Schwartau considers the Total Cost of Ownership argument to be Apple's killer punch. He says: "Why should a company pay more than $2,000 a year for the PC support of a clerk who only uses web applications when a $500 Mac mini will do?"
