After nearly a full day of using it... the fingerprints aren't as bad as I thought they would be - part of the issue might be just how well lit these YouTubers setups are! Yes, it can pick up marks, but Midnight is a very changeable colour depending on the light. I'll see what I think is a smudge when walking back to it, but then I can't see it unless I go looking for it. Not sure if that makes sense or not.
I love the colour though. It goes from a very dark black to a metallic-blue depending on the lighting.
A minor thing, but the new Air plays Football Manager just as well as the MBP 14 & 16 in terms of processing speed; match interface smoothness and there's no fans which I'd occasionally get on the 14 during the matches. The laptop warms up a bit while playing but its not hot like the old Intels used to be.
It also cools down very quickly which is nice.
As others have remarked, the screen is nice; its very light when using on the lap and picking it up with one hand from the corner; speakers are ok but nowhere near as good as those on the Pros; its incredibly fast and responsive, just like all of the Apple Silicon Macs are.
Magsafe... why did Apple not put a colour-matched usb-connector on the cord? Its a minor thing, but really stands out.
All in all, really pleased with it.
