I don't think it's that much of a rip-off. You know, just because something looks good, it doesn't mean it's a total rip-off from Apple. Apple laptops look good and so does this one. Yes, there are similarities, and Apple may have been the inspiration, but I don't think this is blatant ripping off. There are enough of differences to show that these guys took the idea in their own direction.
I'm not going to condemn them to fates worse than death for this. If we want to talk about ripping off from Apple, there are a lot better examples. <cough>Windows!</cough>
And remember, copying is ok as long as you make things better (or at least just the same). That's what Apple did to Xerox and I think that the Asus folks got as close as you can to doing that as possible, considering the incredible limitations of running Windows.
