The Enterprise Desktop Alliance has published survey results which claim that Macs will be the fastest growing systems in the enterprise through 2011.

The EDA claims tech purchasers now see the Mac as more productive machines, and are finding tools to integrate tham into existing networks.

Macs will climb from 3.3% of all systems in 2009 to 5.2% in 2011. Those figureds may be small, but the survey also claims 25% of all new systems to be added in the enterprise will be Macs.

“Much of the growth in Macs will happen in organizations that already have Macs installed,” EDA explain. “The median percentage of Macs in those organizations will double from 5% to 10%. In addition 65% of the respondents had at least some Macs in their organization, and the number of organizations with a measurable proportion of Macs will grow to 70% by the end of 2011. While growth in computers overall is softening from 6.1% in 2010 to 2.9% in 2011, Macs will show 40% and 23% growth in those same years.”

In other results from the same survey conducted in January 2010, IT administrators who had both Macs and PCs asserted that Macs are less expensive to manage, agreeing that they are easier to configure, require less time training and troubleshooting, and generate fewer help desk support calls than Windows systems.
