I mean honestly I am too busy working to ever notice the key sounds on a keyboard. If it works then it works.Sounds like we are lucky that stuff like this is not an issue to us and others. I would never have believed this could bother any one until I read this here.
In a way this is almost a compliment to Apple, that people have to look so far as to listening to individual key sounds to find an issue... Just type on the dang thing, and if it works it works. Heck, every keyboard I have probably makes noises, my Logitech keyboard, my Levono work machine, my old Apple bluetooth keyboard. They kind of are supposed to make noises.
