This bezel-free idea is, quite frankly, stupid. Bezels provide 4 highly desired benefits:
1. Physical protection from damage and repairability.
2. Location for devices such as mics, cameras, antenna, and others. Super thin bezels result in notches, nose cams, and compromised components.
3. On touch screens, they prevent accidental presses. My current A8 tablet has so little bezel, it infuriatingly registers erroneous taps constantly.
4. They provide a visual break with the surrounding environment, making the edge of the display obvious. This is critical for optimal UX where user rely on the ability to "slam" their cursor to an edge to use a control panel. If you can't distinctly see the edge, that gets much less useful.
None of these are disputable. 1-3 are self-evident, and 4 is easily provable in a trivial test.
The Johnny Ives inspired stupidity of "thinness at all costs" has thankfully run its course. Let's hope the bezel-free group-think also subsides when people recognize what they want only makes their lives worse.
