Intel is giving PC builders a strong financial incentive to support its new ultrabook category and get more systems like the MacBook Air, those in the notebook industry alleged Monday morning. The company has reportedly "invested heavily" into marketing the ultraportable PC idea and courting the largest companies to have them sign on to the idea. Many of them don't believe they can match the MacBook Air's $1,000 price, Digitimes says, and are testing but not necessarily producing ultrabooks of their own.
