I think Apple's clear use of Dieter Rams' design language is more of an "homage" than a "ripoff". The fact that the Apple products and Braun products are separated by decades and in different product categories makes a difference.
Disagree, in at least terms of the Calculator - that's not homage, that's blatant copying. Colors, identical, button shape and layout, identical, ratios, identical. The thing looks like someone traced it in Photoshop. That's not "homage".
