I stopped reading when I saw the second paragraph:

[Linux fans'] mission: to replace Microsoft Windows and proprietary applications with the Linux operating system and freeware. [...]
Linux fans don't try to replace Windows for everyone. Linux is just an alternative, among many others, for those who WANT or NEED something else, including the effort to learn, tinker, patch and develop on your own. If you're perfectly happy with Windows, stick to it, nobody's forcing you to go any other way. If you're happy with your car, all the car tuning enthusiasts won't force you to buy a chassis and a kit car and build your own, just because this option exists.

Unfortunately, with all due respect for his professional achievements, Mr. Rod Kovel ventured in an area outside of his expertise, blasting a commentary started on assumptions proven to be wrong from the second paragraph. A waste of time for writing that and a waste of bandwidth for opening it in my browser, IMHO. But this reflects the general view over Linux: everyone believes they're a computer specialist when they learn that triple-clicking in Word selects the entire paragraph, so then they venture in a Linux LiveCD only to run back to Windows in 30 seconds screaming with anger.

Bah.
