Re: Weird, isn't it.....
It is an odd observation, but yes. Android and IOS are so prevalent that in order to be different and individual WP8 and HTC/Nokia colours is a way to express that individuality.
Apple is no longer cool IMO, it's common, mainstream, mass market. You cannot be a premium brand if every bugger you see has one. Samsung for example, never tried to be a premium brand, again IMO, they wanted mass market numbers.
So in order to be different, the only real standout differentiator is WP8, rightly or wrongly.
