Re design aesthetics what is the most "MacBook like" PC notebook?

The Apple MacBook notebook has many attractive aesthetic design elements that admittedly cause some envy in PC notebook users like myself. Primary among these design elements is the fact that it is very slender and light, and is quite elegantly styled.

I saw this ad yesterday for to what appears to be HP’s multi-media kinda-sorta take on Mac design aesthetics and functionality called theHP Envy 15 and wondered what other PC notebook manufacturers have done along these lines. Any other candidates?
