Dell Adamo XPS ultrathin Laptop

Dell teases the new 9.99mm thin Adamo XPS, its about half as thick as the MacBook Air. The Dell Adamo XPS ultra-thin Laptop is thinner than the new Sony VAIO X Series Laptop. I think the Adamo XPS is a great alternative notebook to Macbook Air, if you prefer to run Windows 7 in thin laptop, right?
