That's what I said in other words - it's for people for whom bigger display is more important than input.

Sad that Jolla's thing with "the other half" didn't take off. Or some other standard way to extend these things.

Nope. It’s still a touch screen. The issue isn’t tactile feedback or a lack of it because with touch screens you can miss the button you’re trying to hit.

A miss is still a miss regardless of the touch screen vibrating or whatever the hell it’s doing to give you “tactile feedback”.

Nothing will change how shitty touch screens are and how easy it is to fat finger. I never had any of these problems on my old phone that had a physical keyboard.

It's not about feedback only, also clear tactile button separation, not registering touches.

Repurposable physical buttons - maybe.

The more expensive way is with them being transparent and having their own small displays or being above the matrix, and has some similarities with what you say, the less expensive way is like Sony controllers.

BTW, PSP Slim was the most usable pocket computer I've touched. Text input was slow, but compared to touchscreens - more comfortable.
