Hard to tell whether you're being sarcastic or not, but for what it's worth I wouldn't say that Apple deserves no credit. (I think they deserve lot of credit, but copying is something they do too.)
I really don't see how Apple's actions some 30 years ago excuse obvious trade dress violations by HP. Even if we accept that Apple "copied" Xerox, it is still clear that HP is grossly copying the iMac design. How is that remotely acceptable?
Sorry, I'm not trying to say that its relevant to any case that Apple might raise. IANAL, let alone an American one. I'm trying to point out that copying is rife (and, I would argue, legitimate) in technology.
