I use a Logitech G613 keyboard. It came with a dock that works fine for setting up my iPad when I want to use it like that. But 90% of the time, I’ve got my iPad in a regular case and use it as a tablet. I take it out of the case when I’m laying in bed and want to use it mostly one handed.
I’m sure there are plenty of people who spend the majority of their time using a keyboard and that makes sense with the Magic Keyboard. Clearly Apple thought of your scenario in designing the keyboard as it appears really simple to attach and detach from the keyboard for switching between tablet mode and quasi-laptop mode.
Most people I don’t think use their iPads as laptops. Speculation, but all the same. The iPad is a tablet first and foremost.
