Yuri Shukost, a former journalist now doing public relations for the Australian Defence Department (and heavy Mac user) wrote something so provocative in comments on a recent post here that I decided to "promote" it for general discussion.
The Linux people make a great show about how their OS can do anything, but as one of them wrote: "It appears if you have the time, you can make it work very well."
Sorry, but most people are time-poor, whether it's at work or at home. I think employers and employees would agree with me when I say the computing experience should be one where a person switches on the computer and they are immediately productive.
No reconfiguring, no wishing for apps that aren't there and certainly not dreaming of an OSX-like interface. Just switch it on, use Office or a design or science or...application at work with OSX Server in the background neatly managing your Mac and Windows boxes. Alternatively, Garageband, iLife, iTunes, etc, etc at home.
Oh, and if there is a problem, most Mac user lists will welcome you open friendly arms and in some cases go that extra half mile to help you out.
The geeks amongst us can go into OSX's Unix-based bowels and tweak to their heart's content knowing that whatever they create could potentially be sold as shareware or better to a large established base. I suspect the reason they don't switch to Mac is the same one given by Windows geeks before W95 emulated the Mac OS - it's too user-friendly; regular people can use it and tweak its innerds. IT snobbery in other words.
As an aside, one of the reasons IT sections hate the Mac is because users can adapt the system to suit themselves, rather than vise a versa. This makes trouble-shooting easier for the IT help desk, but creates aggravation at the coal face.
In the end, "Think Different" really means "do it your way straight out of the box". That's why Linux is considered geek territory, while Windows grates. It's also why I'm reminded of the quote: "lies, lies and damned statistics".
