My pink diptoh has "faded" a lot too, and I can easily see the contrast because a small area just around the switches is close to the original colour because it has gone through less frictions in my pockets. I still like it, but it definitely does not look "brand new" anymore, just by the sight of the colour (which is actually less agressive and fancy, so for the pink, that might be a good thing!).

I have not noticed colour-fading with my black toholed from Kimmo, but I don't remember if it was from Shapeways or some other manufacturer, and I'm not even sure it's the same material (it feels different). Kimmo already answered to that actually, but I don't remember his answer.

Thanks for the updates Dirk. What's this carbon-fiber-like backplate in a pale/whitish colour in the Kickstarter update?
