Not a developer at Apple, but I've been using Magic Keyboard's (without numpad) for about ten years now exactly because it has the same layout as every Macbook I own(ed). If they were to ever make a numpad version with the fn key at the same place I probably wouldn't switch either because I would just be trying to hit the numpad when I'm on the laptop's keyboard.
I didn’t think they’d be using Mac minis, Studios or Pros as such.
They can’t all be using the little mini Magic Keyboard or working directly on their laptops?
Can they…. :-O
