Let's also remember the notch. The thick thumb-shaped cut-out housing two front-facing cameras and two sensors inspired sneers when Samsung first showed off the Fold prototype in late February. Onlookers fretted that it looked cheap and would get in the way.
People also had words about the air gap, the little loop of open space at the Fold's hinge end that's wider than the end where the screen sides snap shut.
