There is a slight difference though, you should still be able to tell distinctly at a distance this is an HP vs. a Mac. Having a high resolution display built into an all-in-one body makes sense to copy, but using the same color scheme regardless of materials with the same shapes makes it look like a copy of an iMac.
I am not disputing that HP made it to look like a Mac. I am only saying that this happens in literally every industry, yet we don't see headlines because some pair of Walmart imported sunglasses look like Oakleys.
