The report seems to contradict itself.
Joe Wilcox used to write for news.com.com.com, IIRC.
From the Macworld link in Todd's post:
The report found that in businesses with 250 employees or more, 17 percent of the employees were running Mac OS X on their desktop computer at work. In Businesses that had 10,000 or more employees, 21 percent of employees used Mac OS X on their desktop work computer.
Mac OS X Server is also doing well with businesses. Nine percent of companies with 250 employees or more used Mac OS X Server, while 14 percent of companies with 10,000 employees or more used Apple\ufffds Server software.
[...]
\ufffdWhat we are seeing is Mac OS X taking share away from traditional UNIX installations,\ufffd Wilcox told MacCentral. In some cases, OS X is taking share away from Windows, as well.\ufffd
Unless one believes that MacOS had something like 17-20% of the desktops in these companies (which seems impossible to believe), then Windows must be losing market share to OS X in those companies. Or, unless you believe that 17-20% of
desktops in those companies were running UNIX. I can believe OS X Server replacing UNIX servers, or even OS X replacing some UNIX servers and some Windows Server installations. But I can't see how to square the circle of OS X having ~ 20% of the
desktops in these companies and mainly taking that share away from UNIX.
Bad editing? Poor methodology (I can see the survey being a bingo card like those used for free industry magazine subscriptions - "Please indicate the all desktop computer operating systems used in your organization...")? Dunno.
After hearing some horror stories about problems with OS X Tiger Server (important configuration scripts that point to nonexistent directories, permissions problems, etc.; stuff that should have been caught in beta testing), I find it hard to believe that it's used by such a large fraction of businesses. Unfortunately.
My $0.02. Sorry.
Cheers,
Scott.
