Mike, in that case the next version of Windows won't be suitable for the desktop either
In most work environments the systems are so locked down that OS competency is meaningless because you can't do anything other than use the apps. And how is using a GUI based app in Windows vastly different to using one in Linux? You point, you click, you type, you save.
Anthony was flatly saying Linux wasn't suitable for use as a desktop system, which is plain wrong. Deployment in specific situations is a different matter.
