There I said it. the term "ultrabook" is a weasel term invented by Intel to distract people from "Macbook Air clone". Anyone who can rub 2 brain cells together saw that the first "ultrabook" Asus UX21/UX31 were Macbook Air knock-offs and the same for the Lenonvo/Toshiba clones. I'm shocked Apple hasn't filed suit and petitioned for an injunction. Sure "ultrabooks" aren't selling at all, and perhaps Tim Cook is more pragmatic about it but Steve Jobs would have taken offense and sued out of principle. "Stop stealing our stuff" was Steve's rallying cry.
