I don't think it's irrational at all. Traditional street shooters have been waiting 10 years for a suitable camera for this style of photography - a fast 35mm lens + good sensor in a small package with an OVF and dials for key controls instead of menus. In essence, the digital equivalent of a fixed-lens rangefinder from yesteryear. Thus far, the offerings in this subcategory have either been too expensive (Leica), or arguably have had too many compromises (4/3). There has been some pent up frustration w/in some photographic circles because with the zillion digital cameras that have been put out to market, why hasn't there been one that fits the fairly common bill that's also reasonably priced? It's not too much to ask, really. And - at least from the looks of things, Fuji was the first one to meet this demand. I would categorize all this as "a high level of interest" and a collective "FINALLY!!!" from the photographic community. It's exacerbated because Fuji makes great stuff, and to most the camera is quiet a looker - something you'd be proud to carry around.
