In all fairness though, Apple copied HP first. HP have had the black screen, black keyboard and silver body look for a while:http://peaknewsroom.blogspot.com/200...ack-slump.html
Whenever the first photos of this generation Mac laptops came out, that was a common observation (comparing to Sony and HP) and that it wasn't a good move as it made them look too much like PCs.
If Apple use HP's style and refine it, then HP use Apple's changes to refine their own brand, it's not fair to say they are the only ones copying. It's true that the changes HP made are a lot closer to Apple than the ones Apple made were to HP though.
It's funny reading some of the comments from Windows people on sites like Engadget. Every time Apple does something, they put it down as too expensive or they don't like the style or just generally hate Apple. Then when Dell with the Adamo, Acer with their Air knock-offs or HP with this come along, suddenly they admire them but casually note that they are a bit too expensive as if Apple rips people off but the PC manufacturers just priced a bit too high by accident.
