In German the word "das Keyboard" refers to the musical instrument.
My reason for preferring mechanical keyboards is due to spinal nerve damage I have as a result of a dual disk fusion some years ago. I have limited sensation in over half of my fingers and the additional tactile and audio feedback of a mechanical keyboard makes a real difference. I tried one of the current MacBooks in the Apple store and it was awful. There is far too little feedback for my damaged hands. I use my current 2014 MacBook with an external Das Keyboard normally, but it is usable when I take it on the road. I'm not convinced that would be the case with the current MacBooks. Not to pick on Apple too much, the standard throwaway mushboards that come with the Dell systems at work are similarly unusable for me.
