Generic design vs Apple design.
From a great distance I know I'm looking at PC/Android or an iMac/iPhone.
For many people buy Apple products because of its physical design and build quality.
I do agree that a < 5mm top/left/right bezels would be nice but the bezel color & non-bezel colors for a consumer device is understandable.
Based in the litany of whining on the "chin" and bezels the ideal redesigned iMac would look like this, a Lenovo ThinkVision monitor
- Color black
- < 2mm top/left/right bezels
- < 2cm bottom bezel
