OM shutter is cloth too, but it never gets burned since it's SLR so sun gets deflected by the mirror. As for other question, what do people think when they see Porsche or Rolls Royce? That it's expensive, fancy and stylish. I guess same happens when they see Leica.I wonder what non-photographers and "point-and-shoot" amateurs see when they look at a Leica or Contax or whatever fashionable camera that photographers tend to drool over. I don't know what they would regard as head-turning, but what photographers regard as beautiful or desirable has to be a learned response. I think anything besides an SLR or point and shoot has to catch people's attention.
As far as build quality goes, I have a Leica IIIf and an OM1. The Leica shutter curtain has a hole burned in it by the sun. The OM1 does not, since it's made of metal. So score one for Olympus.
