Apple MacBook Air
Apple CEO Steve Jobs holds an envelope containing the new MacBook Air during his keynote at the MacWorld Conference in San Francisco. The super-slim new laptop is less than an inch thick and turns on the moment it's opened. MacBook Air measures 0.16 inches (0.4cm) at its thinnest point while its maximum height of 0.76 inches (1.93cm) is less than the thinnest point on competing notebooks.
