Not entirely dissatisfied, but disappointed.
Functional keys, cursor, home/end/pgup/pgdn are painful. The default layout is complete garbage. I made 3 iterations with functional keys over 4 months, still struggling. I connect the kbd to the laptop via the monitor, and recently noticed myself switching to the laptop to get things done quicker.
This fad completely mystifies me. Why would anyone want fewer keys and less keyboard on the desk?
I'd understand immediately if these were intended to be portable units, but I've never seen any of them billed that way.
What I, and presumably also the previous poster, don't understand is using the 60% keyboards that remove so many more keys than just the numpad.
I mean, if you're happy with it then great; it's your keyboard. But I just don't understand it.
Many keys means you'll have to move the hands to reach the outermost (or at least rotate the hand around it's "heel" bone). It limits speed and adds to fatigue. When there are less keys, your hand does not need to move/turn to reach, but you'll need 1-2 extra layers and modifier keys (most users put them on thumbs pad). This will take some time to learn, and it's not clear how to organize them.
So this is a fundamental problem: many easy to use keys vs fewer keys, less reach distance but harder to learn.
I've recently emailed the ZSA team about my struggles with text editing, and they suggested me examples how to overcome this with an extra layer specifically for this. [2]
