Yes, but they don't do that on other models of iPad, not just the phone, and again, most people put these things straight in cases, so they've usually (and correctly, despite complaints on Web forums) designed their devices so they won't be too bulky once a case is added, past the early generations when they kinda needed the bezel for space reasons (though, again, even the now-ancient first-gen mini barely had side bezels)

They look pretty much like the bezels on all the other iPads with no home button, just not scaled down to the form factor of the iPad mini.

Which makes sense if the purpose of the bezel is to provide a gripping surface.
