There’s a lot of iconic problems Apple has had with product launches in the past (attenna-gate and butterfly keyboards are some of the most obvious recent ones), but I cannot for the life of me understand how something like this slips through in 2023. They must have a thermodynamics team that helped engineer the chassis, and the SoC team must know the thermal output of their chip. Did they just not test the device?
I don’t know. Depending on where you live, that sounds about on the mark for what you bought. Groceries are getting expensive.
