A couple of weeks ago, I proposed that I&O Professionals should repeal Mac prohibition and find ways to empower employees who are choosing Macs in increasing numbers and bringing them to the office. This was based on fresh 2011 research with Forrester clients, vendors and survey respondents, and concluded that not only were the numbers of Macs in enterprises increasing rapidly, but that the people choosing their own technology for the office, are often the highest performers.
Philip Elmer-DeWitt of Fortune's Apple 2.0 picked it up right away and made a very astute observation: that Forrester's stance on Macs in the enterprise had seemingly flip-flopped. His conclusion was based on a 2007 Forrester report on enterprise desktop trends in which Forrester observed: "Macs can be ignored for all but niche business groups." The conclusion was based on the data of the time, which showed Microsoft's enterprise desktop market share at 95%, but also noted that Apple's had doubled. We also observed in the same report that "Microsoft is not innovating," and "Vista is having a tough time in enterprises," based on data which showed slow uptake of Windows Vista and Internet Explorer 7.
