I thought I had this figured out. I was making a hard-headed decision to buy a refurbed M1 MacBook Air with 16GB RAM for half the price of a new M4 one, for reasons I’ll explain in a moment. But, ironically,

The MacBook Air M4 continues the trend of bringing incremental upgrades but what are these differences between the new M4 and the older M3 and M2 models?

At the risk of repeating myself from Engadget's MacBook Air M1, M2 and M3 reviews: The M4-equipped MacBook Air is a nearly flawless ultraportable. Even better, it now starts at $999, which is $100 less than before.
