Wow, my drunken thread made it to two pages! Ok, here's my take:
I consider the X100 to be 'retro' because it has several of the features that were far more common in classic rangefinders (manual dials, chrome and leather finish) that are absent the vast majority of cameras today. Having said that, Fuji benefits from the association of leather and chrome with Leica quality.
Anyway... I think the style of the X100 is a work of genius. It's the perfect way of differentiating it from other mirrorless cameras, and let's not forget that viewfinder. Still, it probably made them enough money to justify the project and to advertise the new interchangeable lens version, and that will be the end of it. Honestly, I hope it isn't. Perhaps the feedback that Fuji gets will convince them and others to keep the classic aesthetics and give the world more beautiful cameras.
