lol, I'm a touched typist and I don't need to smash the keys though at times, I've gotten mad like the hulkIt's actually very easy for it to be just as quiet as any other keyboard if you don't smash down on the keys like an enraged hulk.
Still, it can be quite noticeable - at least from my informal and short interactions. I don't own a new MBP, so all my opinions are based on how I used them at the Apple store.
