I'll work on a white one in CS5 here in a moment, but my work may be cut short as I have to be somewhere in a little bit.
I voted no. I think the iPhone barely manages to pull the white color off. To me, most mobile devices look incredibly cheap and tacky when they're lightly colored, (white, pink, lime green, whatever). I wouldn't be able to stand staring at the device while watching media or doing anything really. The color would constantly nag at my vision. White/Pink PSP, anyone?
I have my old LG Voyager Titanium and I wish I could have gotten the older black one. It makes it look all, "business-y," and boring IMHO. Unless Motorola can pull off a really nice color scheme, I wouldn't want any kind of silver or chrome finish. Perhaps it will look significantly better with this phone, but I'm still weary.
I would, however, be interested in seeing actual solidly colored versions of the phone. Blue, red, etc. I wouldn't necessarily want one, but I imagine they would look pretty sweet as long as button and label colors were changed correspondingly and the main color was bold, instead of some light version.
