> One of the things macbook users praise the most is "build quality", which often means the solidity of the device, lack of flex, etc. These quality features are, in part, achieved by the same choices that make it hard to repair. Ease of repair and "build quality", are to some degree (although not entirely) tradeoffs against each other.

You're making an oversimplification. You could make a heavier, thicker device with those same qualities that was repairable.
