Nice idea, but many might not like to have their phones 'naked' in their hands... thus, those might not sell well... this being a business proposition, the ROI counts.... so, how many manufacturers would like to go into that kind of trouble just to sell a few handsets? And N9 / Lumia being 'unibody' makes it all the more complex... else, clipable covers could've worked [like we had on a few erstwhile models]. Then again - isn't there a wholesome charm in our 'colored' N9s? That most in the mkt today r [drab] Steel / Grey / Blacks...
