Yes, Steve, most of the world is ignorant of the smoke phenomenon. My customers usually fail to understand how time consuming and expensive it is to get the smoke back in when their equipment fails.
Let's be honest though, dark suckers can be a real problem. Manufacturers for some unknown reason always mount them in the most inaccessible parts of their equipment and, even though relatively cheap to replace/repair, the effort involved in effecting such a replacement is dreadful. Many of these devices don't break their smoke circuit, it's just that the smoke conduit has failed (but not leaked); a repair is usually a matter of a mere minute or two once you have accessed the darned thing.
Reflecting telescopes are a basic form of dark sucker as most on here would be well aware - but the general population is not. So when something baffles you it's why the term "It's all smoke and mirrors" comes to mind.
