The original reason for this was that I didn't want to spend all that time getting pass-through charging to work, so for charging the keyboard needs to come off.
But this "quick release" design has the advantage that you can use the phone without keyboard when that's advantageous, e.g. when I want to type really quietly while in bed.
This also gives me a direct comparison between physical and virtual keyboard, that you usually don't get on a pure keyboard phone. And I have to say, typing on the screen is a PAIN compared to the physical keyboard.
and the ability to customize what’s in those top two rows would be amazing.
