Have you noticed an increased presence of Apple products in public spaces and workspaces in the last few years? Turns out that 21% of information workers are using one or more Apple products for work. Almost half of enterprises (1000 employees or more) are issuing Macs to at least some employees – and they plan a 52% increase in the number of Macs they issue in 2012.

Sure iPhones and iPods are ubiquitous in public spaces, but Macs weren’t common, especially in the workplace. I started seeing lots of Macs in startups I visit such as Box and Evernote in Silicon Valley, and Backupify here in Cambridge, Massachusetts. But it got really interesting when I started seeing a few employees at large established tech vendors using Macs, where corporate IT usually doesn’t support them and seeing a disproportionate number of Macs among Starbucks loungers. The clincher was the behavior of CTOs at two large infrastructure software companies that have a group of CTOs that work across the company. In both cases, almost all of them were using Macs – and they were making fun of the remaining Windows holdout for using a “typewriter.” Of course, the iPad added to this phenomena, which is visible when you walk down the aisle of long haul flights in the US – there are lots of iPads, especially in first class.
