R.E. Warner politely responds to Neven Mrgan:
I have great respect for Neven Mrgan as a designer. He’s an accomplished artisan and not to be trifled with. However, his post on how the design of iOS 7 icons is “wrong” is misguided and I feel the need to address why I think that is, because I often see designers get caught by this particular hobgoblin of consistency—that a design just “feels” right to them without offering any rational justification. So, I feel it’s more constructive to write an extended objection here rather than leave it my less than poetic tweet.
Warner argues that Mrgan is basing his sense of wrongness on familiarity and not function.
