So the inter-company envy is coming back, like when iOS copied flat interface ideas from Windows Phone. I am wondering why we always end up with unified bland stuff instead of many possible variations so that everyone can choose what they like? It seems like nobody wants to take risks anymore. I remember time when every single app had completely different interface; these days everything looks alike. Even if it is more economical, one size doesn't fit all.
