i got my 1.83 MBP about a week before the first price drop/speed bump [early May] (ended up being compensated). to my chagrin, it was an early build week, and had the dreaded whine. i toughed it out, and waited for the 'fix'... i brought my mbp into the campus hardware service centre at my school [Dalhousie in Halifax, Nova Scotia], and pretty much told them what the problem was, and what they needed to order me, etc... they phoned me yesterday morn and told me my logic board was in. so i brought it in, and within a couple of hours they had the new board in. after a solid 24 hrs with it, I can say this computer is QUIET. dead QUIET. i can't believe the difference. brand new computer. while i will admit that it seems a bit warmer (could all be in my head), the trade off is worth it. anyone with a whiner, just get it in for the l.b. swap, and you'll be pleased.
