Apart from watches, Braun design language last couple decades have felt pretty uninspired.
I agree. However since 2009 the Head of Design has been Oliver Grabes, and I love where is he heading. He started to think more about legacy Braun design and started incorporating old design elements in their never elements.
Important product categories are different, households are different, mass manufacturing processes are completely different. Braun pushed the envelope so much. Designing products now using the language of the 20th century seems...to miss the point at the least.
Nothing against Oliver's work, but for Braun to be a true design powerhouse again would take a clean slate, and I don't see how that can be done.
