The last intel MacBooks were sold in 2020. So Apple is comparing a new 2025 Air with a state of the art chip to an approximately 5 year old MacBook Air with an Intel processor that, a few months later when the M1 appeared, would be relegated to the dustbin of history for most Mac buyers.
Sure, most Mac users don’t upgrade every year so the year over year performance gain isn’t relevant to most prospective buyers. But how many of them are running MacBook Airs with Intel processors as their daily drivers? A few folks in this thread said they weee, and that’s great. But I’m guessing they’re in a tiny minority of Mac users.
I’m happy to be wrong, though. I love hearing about folks using their Macs for 5+ years. These machines are well built and the M series chips have long usable lives. I have an M1 MBA that can handle my daily workflow well. It’s nicer on my 15” M3 MBA, but the M1 is no slouch.
