Feels like the MacBook (Air) is the product Apple should knock out of the park in terms of attractive design. It will be plenty powerful with an M2 chip, that should like M1 be very frugal in terms of power consumption and cooling requirements, so this laptop can be very thin and light, with a long battery life.
You look at the current MacBook Air and if you lose the wedge shape (shame, I like it), it means Apple can stick some battery under the trackpad, cut down the size of the surrounding batteries, stick a low profile fan assembly in instead of the heatsink, etc., etc.. I would bet Apple could could shrink a 13 inch M2 MB down to something a bit closer in size and weight to a 12 inch MB with virtually no compromise.
