I wonder how this would feel in hand, grip seems to have unbalanced weight when I mimic on my iPhone pro max 11. Like it wants to tip over but maybe if you really have something physical at the bottom it is not that bad.

Blackberry sacrificed screen for the keyboard so balance was all OK.

I also caught myself thinking these buttons were too round and too tiny as compared to my on-screen keyboard. Also not having the luxury of seeing all my special characters appear on the keys when pressing the 123/#+= etc to toggle keyboards would be something to get used to. E.g. Type a {} or ~.
