I personally couldn't care less. Does not bother me at all with my Air 2. But I know it aggrevates some people enough to want to rip their own hands off. So for all of you who are sensitive to the speakers vibrating I'll give you a warning that the speakers on the Pro 9.7" also vibrate. By the same amount as the Air 2. I checked it out in store today. Just a friendly warning for y'all!
