How was it stupid? Aluminum is a lightweight metal and yet strong. It is also highly recyclable.
And from Apple's perspective, it being metal and acting as an external heatsink is a bonus for them to get things as thin as possible.![]()
Aluminium is great for some things and useless for others.
Unfortunately, when cut into a thin shell (like a thick egg shell) for the external use of an item, one knock and it's dented.
Pretty useless for anything that get's knocked or bumped about. Plastics can be much stronger in this use.
Unfortunately we STILL have this "Plastic = Cheap" attitude rather than what's the best product for the job.
They could make 24 carat gold cases but they'd be useless.
