Thank you for the complement about the article.

I really can't imagine why you'd want to come across as having not written it

I didn't immediately want to take credit for the article because as yerricde, so many people had put me on their foe lists for allegedly repeatedly ramming the issue down their throats on every single music-industry-related article. I guess they just couldn't handle the facts about the copyright incumbents' monopoly on songwriting.

"don't have computers in the currest case"

Do you mean "current case?" Preview is your friend.

It's silly, really, to claim that Windows has some sort of UI or usability advantage over Linux or *BSD or any other OS. As you said, these are people who aren't used to any computing at all.

I bought my old grandmother, who had never owned a computer, a Linux PC. She has no problem whatsoever using it - she can run KDE and all she really needs to do are run the Mozilla and KMail programs, which she learned fairly quickly.
The truth is, when you're teaching a person how to use a system, much more important than the perceived usability of the system are:
A) What's the former experience of the trainee? If they've used Windows mostly, they'll be used to Windows. If it's Linux, or MacOS, they'll be used to those. I often have trouble using Windows or MacOS X because I'm so used to X-style cut-n-paste, terminals, etc.
But if they know nothing about computers, MacOS and Windows and Linux will all be just as alien to them.
B) What programs are they using? Most people use a mail client, a browser, and a word processor. The main thing you need to consider for these people is the ease-of-use of the actual programs they use (not the OS, not the UI) and teaching them how to get to those programs.

Again, just my 2,000 Argentine pesos...
