Apple CEO Tim Cook has sparked speculation with a teaser about a new product announcement. The phrase "there's something in the air" has led many to believe a MacBook Air with the M4 chip is imminent. However, it's essential to note that there's no concrete evidence to support this theory.While some speculate that Cook's message might be related to an upcoming MacBook Air, others consider alternative possibilities. The iPad Air launch window also looms, although it's believed to be less immediate than the MacBook Air.Cook has previously employed similar teasers before major product launches, including the iPhone 16e announcement last month. Without further information, it's challenging to separate fact from speculation.
