Acer's creator Stan Shih tried to stir controversy Friday with remarks once again trying to dismiss primarily Apple-driven technology. He called tablets like the iPad, and now the ultrabook category created by the MacBook Air, "short-term phenomena" that would go away. The conventional PC was the cornerstone of technology; not only did the tablet and smartphone come from the PC, but everything had to go through it to make value, Digitimes recounts him as saying.
