The look of Fuji X-series cameras, and their lens line, is very stylish. People LIKE good-looking cameras, with traditional camera-looks, not "consumer electronics looks". Seriously, there is a HUGE advantage to manufacturing,marketing, and selling a good-looking product line, as opposed to an ugly or weird-looking product line. Many people value beautiful design...Fuji obviously understands that.
I used to sell cameras and video gear at retail...people comment on the outward appearance of cameras, just as they do clothes, cars, houses, and so on. Present a handsome camera and an ugly or new-fangled styled camera on a sales counter side by side...the customer will almost always avoid the ugly or new-fangled camera, and will instantly gravitate to the better-looking camera.
A great example: the Nikon 4004 and 6006...butt ugly and "new-fangled" styling...EXTREMELY difficult to sell against Minolta AF SLRs and Canon AF SLRS...the 4004 and 6006 were UGLY! The Canon EOS 620 and 650 were sleek, the Minolta Maxxum 5000 and 7000 series, and their lenses, were SEXY!!!
