I don’t see business going to an unsupported (or even supported) version of Unix on the desktop any time soon. I was just answering your issue of why Unix is more secure than Windows. Unix is inherently more secure than Windows, because Unix lacks a registry. That’s just a fact. MSFT is improving the security of Windows, but their efforts are mostly just band-aides on a sucking chest wound. Windows has many fundamental security issues in the design of the OS - and two of them are the registry and active content.
The business sector will continue to tolerate Windows until such time as an alternative arrives on the scene that a) will migrate their applications, licenses and data with a minimal cost, b) have a lower TCO than Windows (which won’t require that it be free, BTW) and c) has good support.
With the increasing penetration of virtualization, issue (a) is becoming less of an issue. (b) is up in the air, and (c) hasn’t materialized yet.
Interesting thread.
Now what would be more of a challenge is to write an article about an OS that is *not* more secure than Windows.
Can’t disagree with anything that you said...
