Fanless, much lighter and smaller. I would.
At almost 3lbs the Air looks the same as my MBP 13, although it has one sided USB-C (which sucks), and it's cheaper (doesn't suck 😀 )
Granted, it's thin-wedge, but the similarities stop there.
But really, this argument is just the same one as before. The MB is not a performance machine. It's a 'small, light, and quiet' machine.
Frankly, I can't believe they didn't update it. But I'm happy. I'll save some money. I just bout the phone, which was crazy 😀
Note: The new Air does have a fan, you can see it on the left.
