Linux is the new Windows XP. "We can't install that web app, we are standardized on IE6 and WinXP until 2035 or the Second Coming, whichever comes first".
Make that just "the new Windows" and I'd agree. There's plenty of standardizing on "Server 2003" and other Windows versions, that didn't stop with XP.
Or, in other words, both platforms have firms that like to standardize on particular versions for stability. Which isn't really much of an attribute of Windows or Linux themselves, really.
