During a recent speaking engagement at the Jamf Nation User Conference in Minneapolis, IBM VP of Workplace as a Service Fletcher Previn said his company is saving even more money than anticipated by trading out PCs for Macs.

After first adopting Macs for its employees in mid-2015, IBM now has 90,000 employees using Macs and is deploying 1,300 new Macs each week. By the end of the year, IBM anticipates that 100,000 of its employees will have made the move to a Mac.

Most assumed that using Macs would be significantly more expensive than PCs seeing as they cost more up front. That’s not the case, however, according to Previn.

Depending on the model, he says, IBM is saving anywhere from $237 to $543 per Mac compared to a PC over a four-year lifespan. The figure represents the best pricing they’ve ever received from Microsoft, he added. Multiply that by 100,000 and you’ve got some serious savings.

At last year’s conference, Previn said Macs require less management and setup effort than PCs even though they cost more up front. This year, he said that just 3.5 percent of employees using a Mac will reach out to the company’s help desk for assistance.

Looking ahead, 73 percent of IBM’s employees say they want their next work computer to be a Mac.
