Apple is planning a major overhaul of the MacBook Air that could see it competing with budget ultraportable notebooks, a rumor floated by Digitimes Research analyst Mingchi Kuo claims. The system would shrink to an 11.6-inch display and would use ultra-low voltage Core iX processors. In spite of the smaller screen, it would be thinner as well as lighter; the design would be advanced enough that lessons learned from its creation would be rolled into other Macs.
