HP Defends New Ultrabook Design Against Noted Similarities to Apple's MacBook Air
I would go back to the TC1000 [Tablet PC] from about 10 years, and that's a tablet. I think if you look at the new Spectre XT, there are similarities in a way, not due to Apple but due to the way technologies developed. Apple may like to think that they own silver, but they don't. In no way did HP try to mimic Apple. In life there are a lot of similarities.
Engadget followed up with Wolff after the session, and he offered some more thoughts on how there are only so many solutions to a given design problem and how HP's design differs from Apple's.
The thing is that you have to design what's right, and that is that sometimes the wedge is the right solution, silver is the right solution. I see a lot of differences as much as the similarities. I think anybody that's close enough to the business sees that there are differences in the design. Ours is rubber-coated at the bottom. We use magnesium; they didn't do that -- they use CNC aluminum. We did a brush pattern on our product; they didn't. We did a different kind of keyboard execution. We did audio as a component; they didn't. So there are a lot of things I can list off that are differences; but if you want to look at a macro level, there are a lot of similarities to everything in the market that's an Ultrabook today. It is not because those guys did it first; it's just that's where the form factor is leading it.Wolff goes on to cite the "form follows function" argument in claiming that there are only so many ways internal components can fit into a notebook and that the wedge shape is a natural result of how those physical constraints manifest themselves in a usable product design.
Responding to comments about the black "chiclet" keyboard on silver body being similar to Apple's implementation, Wolff notes that a simple color choice doesn't amount to copying and that HP's work with chiclet-style keyboards dates back to the mid-1980s.
HP is far from the first ultrabook manufacturer to be the subject of questions about potentially copying Apple's MacBook Air. Most notably, ASUS was one of the first company's to show off an ultrabook design in the middle of last year, with that design bearing an even more remarkable similarity to the MacBook Air. PC manufacturers have been rushing to bring ultrabooks to the market, now taking advantage of Intel's new Ivy Bridge processors in an effort to take on the MacBook Air in what is predicted to be the future of notebook computing.
