That's overstating it a bit, but close to the question. I was (and am) genuinely interested in whether people have had many problems with so-called non-weather-sealed cameras. Ade-oh's response about Iraq, and RichC's story about Mt. Etna, to say nothing of Brian's story about the water-fight, suggest to me that even a 'non-weather-sealed' camera can, with a little care, intelligence and foresight be used in surprisingly harsh conditions.
It's the refusal to exercise care, intelligence and foresight that I regard as the macho fantasy. In the late 80s or early 90s, when I lived in Guadalupe, California, I saw a young reporter wandering around at the Passion Play wih no lens on his Nikon. Guadalupe is pretty dusty. When I asked if he wasn't worried about dust getting inside the body, he chewed his gum with elaborate nonchalance and said, "Nah, Nikons are tough" -- with the implication, of course, "And so am I. I'm a hard-bitten reporter, and not, contrary to appearances, a stupid kid." In other words, sure, weather sealing is a good thing. But so is intelligence.
Fifteen or twenty years ago, a major US camera importer told me, "You can sell cameras using the fear factor. Say to someone who is perfectly happy with his camera, 'Yes, but can it do this?' (which the camera you're selling can, and the one he is using or considering can't), and regardless of what 'this' is, even if he's never thought of doing it or needing it before, you've planted the seeds of doubt in his mind." Weather sealing is, I suspect, for most people, the fear factor in action. So I was trying to gather some evidence on one side or the other.
Let's face it. Technically, photography ain't that difficult, and composition is something you learn with practice. Wherever possible, I'll try to help someone with technical issues, because we all have to learn sometime. But I'm increasingly interested in how and why people take pictures, and even with what cameras they choose and why, which explains threads like this.
EDIT: Steve's point is well taken, but again, I wonder how much actual evidence there is of electronic cameras being less reliable.
