I would assume he is talking about the Magic Keyboard 2.0 which is the newer version of that one. It is widely considered to be an excellent keyboard and many people (rightly in my opinion) don’t understand why they just don’t put that keyboard in their laptops. I type on the MK2.0 and love it but keyboards are a personal thing and there any many thin style ones that I just can’t type on, and don’t get me started on “mechanical” keyboards, awful, loud, dreadful RSI inducing things (for me).
