I love when Topolsky talked about design, like how Material Design is so superior to iOS (No, it's not).You must love it when tech journalist talking about things they have no clue about. Looks how he dress himself, is there any design in that?
Thinking about it some more I think Apple couldn't care less. They're in the process to move all the screens to OLED at some point in the near future. Next year with iPhone 7 possibly. ( the market of the Watch is still too small)
