We already have here in these forums. Wont do any good though, it's not a general population in any case.
I have no idea if it's typical or not, I have only a sample size of one. But one thing I do know is you wont know yours is noisy or not until you take it out of the box! Maybe it wont be, maybe it will, and maybe if you have one with the whine and you can tolerate it like I do. It's a good machine, so give it a chance at least! I have many computers available to me at home, yet the studio is the one I use most of the time.
If I had to do it all over again, I might have gone with a MBP and use it as a desktop, but that ship sailed a long time ago. I actually had a 14" MBP on order when it first came out, but decided against it for other reasons, so I cancelled.
