"I have always regarded Apple products – and the kind words Jony Ive has said about me and my work – as a compliment. Without doubt there are few companies in the world that genuinely understand and practise the power of good design in their products and their businesses. [...] I am always fascinated when I see the latest Apple products. Apple has managed to achieve what I never achieved: using the power of their products to persuade people to queue to buy them."[1] --Dieter Rams (Braun designer from 1961 to 1995)
Dieter Rams made toasters and radios, and Apple extrapolated his design cues to things he never made, like laptops and trackpads.
That's a far cry from HP taking someone's design decisions for a all-in-one computer, doing no extrapolation, and using them to make a competing all-in-one computer.
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".
