You're outright inslting toward any gnu project member
Really? I have nothing but the utmost respect for Miguel de Icaza (GNOME member, founder of GNOME), or David Schlesinger (GNOME advisory board), or the entire Mono team (not GNU, but affiliated fairly closely with GNOME).
(seriously, an attack on body odor? All crazies?)
It stops being an attack when you've been in the same room as them. Seriously, I've seen RMS do his foot-picking thing...
You're assuming you've written more free software than me,
No, I'm assuming I've written more open-source code than you have. These days, I specifically license stuff like
Sharplike to be 100% incompatible with the GPL, so it's certainly not free software. But through Summer of Code I've still probably written more "free software" than you have--so, what have you worked on?

My open-source code has been linked around before. My bona fides are established. What are yours?
or that I ever will (you don't know me).
Sure, you might write more than me someday, but I kinda doubt it. Mostly because the people beating the "GO USE LINUX" drum never do. You could be the exception, but you gotta do the work to
be the exception. Better get started, huh?
"the desktop software is a screaming bloody aborted fetus on its best day ".
I'm so sorry you are upset by description, but that's a pretty decent metaphor for it when you stop and think about it. If you're getting offended over the characterization of
some source code, don't you think you should probably evaluate your priorities a bit?
(And to forestall the inevitable:
I am not offended. I enjoy these conversations, because it's rather personally rewarding when somebody goes "shit, I get it now!".)
You're calling me and obsessive loon, a fanboy, and you still don't see what's wrong?
Well, yes, I have called you a fanboy. Your behavior is indicative of it. I haven't called
you obsessive, though if you really think the FSF and GNU are all that you just might be one of them. I
have indicated that people who have work to do don't really want to fight with a Linux box
I won't loose my temper you know?
But I actually curious : what are you trying to achieve?
Not much at all. Once in a while a fanboy wakes up, but it's pretty rare. I've said my piece, and defended it when other people tried to attack it. And, without tooting my own horn too much, I'm not seeing much in the way of effective counterarguments.
It's not like he is very interested, and a blind guys could see you're being overly partisan.
He's clearly not interested. My concern (and it's really a mild one at best) is that somebody else might go "hmm, those Linux guys are persuasive" when they're blowing smoke up the reader's ass. Because they may not have the technical acumen to know when you lot are in over your heads, too. Which you very much seem to be.
It's not like you can acually believe what you say : more than a few organization use linux on their desktop, including the european commission, the French and Belgian police, google favor Linux too, my university use it as it's main os,...
Google actually favors OS X internally; you can get a Linux machine if you really want, but I saw a hell of a lot more iMacs and Mac Pros than I did anything else the last time I was in Mountain View.
And, yes, in a large-scale organization where the use case is extremely limited and regimented, you can implement a mediocre (and thus probably acceptable) desktop via Linux. Great. Awesome. Mediocre. But here's the thing: that doesn't scale downward, and it doesn't scale in features. Sure, the cost savings in a large organization might sometimes be desirable (not so for an end user: you already bought the OS with the machine), but
these are home users we're talking about. It's unsuitable for a general-purpose machine. Games. Office productivity. Line-of-business (line-of-education, in this case) applications. You can point to the EC and the rest as "oh, look,
they use it!", but
they are not people buying a computer to use while sitting on their couch.
(BTW, to build on your point: you know that Munich in particular
has been a total fail train, right? They've basically admitted at this point it would have been cheaper to stay with Windows. The EC's use of it has been anti-US more than anything else (not wanting to patronize Apple or Microsoft--in their position, a politically expedient act, can't blame them). Oh, and the Gendarmerie's numbers as far as "money saved" are really interesting seeing as how it worked out to something like a $12,800 "savings"
per computer.)
There is a lot to add there but it's not the point : you're not even trying to be objective, Why?
Because I've already been to this rodeo. I was one of the people who cheerled for Linux desktops, rah rah rah--I even took a (stupid) financial hit, charging people who were using Linux machines
less because I "enjoyed working on them." And eventually, like most teenagers do, I grew up a little bit and went "man, I'm being totally stupid." And it was stupid of me. If you want to actually take anything remotely close to an "objective" look (not like
you do--"you'll get a lot fewer crashes!" is FUD of the first degree), you can't
not come to the conclusion that damn, this is going to be a waste of time for people who don't already want to be using it in the first place. (In other words, if you're not somebody who
wants to be using it--and Joe Schmoe end-users aren't those people--Linux is unlikely to be of value to you.)
