Yes, you mention apple, google and microsoft. I am under the impression that designers work on accepted (by big/famous companies/personalities) designs within the design community. Are these trends simply designers daring to be original, or can we trace these new trending designs back to a single influential source? Or maybe does the design need to exist on said influential sources for shotcallers to dare say OK ship it!
