Seriously???4. The power button. Maybe not a deal breaker but it staggers me that anybody would try to defend this stupid decision (presumably to save a few cents on each unit by not having to incorporate a proper button on the case*). I mean... "you don't need a power button, just put it in sleepm so we're leaving it off" would have been a courageous decision to discuss but accepting that some people need a power button ...and then putting it in a ridiculous position is just plain bananas.
How many times a year do you use a Mac power button (not for fingerprint recognition, but to power on/off)? Once? Twice? I think it's probably been twice since I got My M2 Air over a year ago.
Clearly they have issues with back panel space. This is a reasonable design call. I don't love it, but as a negative it's too small to measure. And actually, it might be a positive - there's no chance of it being bumped by something else on your desk. I've seen that happen, though not to a Mac.
