I understand that he hates the "flat" design trend. I know he loathes the "Californian minimalist". But I still can't quite grasp exactly what it is he DOES like.
His blog posts include lots of images comparing iOS icons to pre iOS7 versions, mostly comparing images without gradients with those that have gradients.
Can anyone actually explain his point? As far as I can make out he seems to be arguing that users would benefit more from design that "pretends-to-be-like-another-thing" rather than "represent-that-thing-as-it-is"; y'know, the opposite of honesty in materials. For the life of me I can't make out if he has a point, or it's just the lamentations of someone who got really good at drawing skeuomorphic* icons and is now buggered because the fashion is now for flat monochrome icons.
* I loathe to use the word like this as I don't believe that many cases that type of design or interface is strictly skeuomorphic, more misplaced metaphor. e.g. stitching on a fake leather notepad=skeuomorphic, detailed drawing of a hard disk drive to represent a hard disk=metaphor
