Sorry, but I hear everyone saying that and I've yet to see one that actually looks exactly like a Mac Book, short of the branding, of course. Sure, they all look alike, but so do Smartphones, at least from one angle. If you want to do minimalist design, you're already limiting yourself to a small subset of possible design elements. If everyone tries to do minimalist design of a similar product, it's inevitable that some design elements will be seen in several of these devices.
Samsung Ativ laptops have the MacBook look with similar profile, color combinations and chicklet keyboard with the VAG Rounded font that Mac Books use. Those are the ones I have seen that share the look the most. Apple hasn't said a word on those laptops yet. They seem to be much more defensive on their line of iPhone and iPad products, which makes sense when talking about Samsung. Apple feels a greater market pressure from Samsung on smartphones than on laptops.
