Yeah, it's a copy. Maybe even an improvement, depending on what Chevy decided to add to the process. Question is, why do people care who copied who? Bragging rights? Justification? Satisfaction?
Personally, I don't care who copied who. Android might've aped some of iOS. iOS might've turned around and aped back some from Android. Whatever. It's all a moot point to me. These big, impersonal, multibillion dollar companies can rip each other off til they're blue in the face. As long as I get a better product from all of it, I don't care.
Now the usual inevitable response to this is "shouldn't Apple be allowed to profit off their own hard work without someone stealing their IP". Uh, aren't they worth 40 billion these days? Don't they control a good 90% of the tablet market, despite all the quote unquote cheap ripoff tablet clones out there stealing their ideas? Are they not profiting enough for you as is?
So once again, why do some of you even care who rips of who?
