I dont see the bezels go away in a long time. Actually I like the look and feel of the current ipad & iphone bezels. It makes the device look and feel more solid. My current wishlist for the upcoming ipads;
-10.5" or bigger OLED screens (with truetone ofcourse)
-3D touch/new iphone 7 style homebutton.
-Huge performance improvement. Atleast 6GB RAM.
-light as possible
-perhaps a wireless charging
I believe my air2 is holding great until i see atleast most of these things happening. I know its not going to be next year but perhaps 2018 or 2019.
