Question: what is the difference between a macbook and a macbook air?
Answer: Portability. The MacBook Pro comes in at 0.61 inches thick and 11.97 inches wide, whereas the MacBook Air is a mere 0.16-0.63 inches thick and 11.97 inches wide. That makes the MacBook Air (very) slightly thicker than the MacBook Pro, but it's lighter at 2.8 pounds versus the MacBook Pro's 3.1 pounds.
