Only if you need instant visual feedback regarding how good you hit the center of the key. For LCDs there are patents for compensating the distortion caused by haptic spherical caps on the touch screen based on a front camera doing eye-tracking. I do not know how good this might work for e-ink, but a consideration could be somehting similar to a screen protector that you place on the screen to enable better typing, and take off for better viewing. Maybe with a hardware button that re-adapts the distortion correction to the current gaze, so you'd press this after sitting comfortably in a chair or such, holding it the way you want to for the next few minutes or longer.
both the voyage and the oasis do have a bezel, if we're using the modern usage of the word, like the iphone 7 has a bezel and the iphone x is bezel-less. The paperwhite, voyage and oasis are all touch screen e-ink kindles that I've owned (I dunno if the base kindle is touchscreen these days, I haven't owned one.)
I don't know if it's required or not, but I think previous poster was suggesting that the bezel was needed in e-ink displays, and all the kindles I know of have a bezel, even though that bezel is flush on the voyage and oasis models. Now, I personally think that poster is wrong, at least if we are using bezel in the sense that the iphone x is bezel-less; but the current crop of e-ink kindles are not bezel-less.
Personally, I think typing is okay on the paperwhite and the second gen oasis... on the voyage and on the first gen oasis, the thing wasn't responsive enough to type comfortably, in my opinion. I dunno if that had anything to do with it being e-ink, though; It could have easily been an anemic processor.
