Is anyone else extremely annoyed about how loud the click on the trackpad is? I went to the Applestore thinking that there was an issue with my particular MacBook Air, but the Genius told me the loud noise is normal. He did loosen and retighten the trackpad to see if it helped the extremely loud click noise, but it did not. I am ready to return my machine in hopes that a new one will be better, or is this not a defect? Is the only flaw on this laptop the extremely obnoxious trackpad click noise? I can't commute to work on a 2 hour bus ride with this sound. I truly cannot believe Apple would allow this, that is why I am willing to try another machine before I give up on this current generation of MacBooks. Is anyone else having this issue/complaint?
