I'm also thinking about chassis rigidity of M2 Air. I mean total thickness is 11.3 millimeters, so basically bottom chassis is what 7 or 8 millimeters thick, so how thin sheets of aluminium is used in the chassis then? I've already read some complaints about MBP 14" and 16" that bottom cover is so thin that it flexes easily when just handling the unit and those are much thicker units.
Just thinking out loud, if the bottom unit has 1 mm bottom place and 1 mm top, it leaves 5 or 6 mm space for battery and mainboard and such... If plates are 2 mm each, then 3 or 4 which I think it is too small, it would be pretty impossible to fit all parts inside and leave room for some battery expanding. So to me it sounds like the aluminium might be pretty thin. That combined with flat design could also make it less rigid/solid compared to old design where these tapered edges actually reinforce structure.
Anyone else thought about the same things? I did not notice any Apple event videos of small reviews mentioning anything about these type of things.
