There is a big diferance between taking a good idea, like the GUI, and running with it (which is what that quote was intended to refer to), and two products apearing to be similar that were in development at the same time. Not denying Apple take the ideas of others, I just think the LG Prada is a poor example, as it was a piece of junk. The bulk of product design in in materials, this is the perfect example. My dad still has my iPhone 2g, and it feels like a solid piece of metal. I still think from a product design standpoint the origional was the best of the bunch.
You could argue Audi stole their grill design off of Rover, as it popped up there first. The Audi wears it better, and is synonomous with them now. They executed the design better, was in development at the same time, but just happened to be slower out the gate.
