Tablets need an edge where you can grip it. Without thicker bezels, it’s harder to hold it without your fingers being on the screen. This is much less of an issue for phone-sized devices.

This has always bugged me.

- Why is grip a feature of the bare tablet and not part of a case accessory?

- Why is the grip point the flat glass front of the display, instead of anything more ergonomic for actually holding it?

Phones don't do this, not even 7" phablets, nor for holding them horizontally, nor holding them with two hands gamepad-style during gameply. Why do tablets?
