...and I'll be sending this one back too. My first one made that stupid little whirring sound, but nothing else was wrong. I figured that for over $2100 I was going to make sure that it was perfect. I got the new one today, and it was working great. Then, about a half hour into my experience, it started that annoying whine again. I quickly installed the mirror widget. I was going to be satisfied with that fix, as it's a fun widget to show off with. Then it started that mooing sound. I had heard about it, but never heard it before. I was pissed off beyond belief. In fact, I still am pissed off beyond belief. That said, other than those noises this is the most incredible computer I have ever owned or used extensively. I love my MBP, but I don't want those little things to keep annoying me.
