Mac OS X *isn't* desktop-ready?

I was reading the Dell Ideastorm today - you know, the one where they give the idea to "Put Ubuntu computers on display in stores" alongside the Windows ones.

And it looks like people will use any excuse to say "Ubuntu isn't ready". Including "But I can't make money off technical support for Ubuntu! The people who use Windows pay me to get rid of their viruses - what would I do if everyone switched to Linux?"

But the most incredible statement made was this:

@sanbha, This Physician works solo so he did not pay to have a developer create the custom applications for him. These are software that he purchased... A couple of them are subscription based. The main software that he uses to record patient data, billing, insurance and schedule patients is only available on Windows and MAC, no support of GNU/Linux, all his other important software are currently Windows only. The fact is the companies that create these boxed medical software have no incentive to port their applications to an Open Source OS, not when a single user box version for Windows/MAC sells for $1000 and support cost $129/hour.

This Doctor do use an Apple as his personal computer that he uses to write his books etc, but not even the MAC has grown up enough to take to work [my emphasis], unless if you work in the graphics department. (Note, I work at one of the largest financial companies in the country and there is only 1 MAC (a colored IMAC) in the graphics department, all the other machines are Windows)

Seriously. This person's view of desktop-readiness goes something like this:

Q. Is it Microsoft Windows?
A. No
Conclusion: It's not good enough for work.

But the thread on Ideastorm has given me fodder for the "Mac OS X desktop-readiness" article; look for an update soon.
