MBP? Very dissapointed!!

I recieved my mbp last thursday after waiting a whole month for it. I opened it and soon excitement turned into dissapointment as I heard the eery whine. I phoned apple and told them about it, the offered to replace or to repair, not being able to guarantee me a quiet mbp I chose to have it repaired. Friday comes and I recieve the box, monday dhl came and picked it up, it arrived to texas on tuesday and by wednesday it was already repaired and come today I recieve my supposidly repaired mbp. Yesterday when I saw that my mbp had been repaired so quickly I was a tad bit skeptical so I phoned applecare where they informed me that my logic board had been replaced. Today I eagerly open up the box, boot up my mbp to find that the whine is still there. The only thing I found differant was my screen saver, mac osx had not been reinstalled nothing. I phone applecare once again get transfered to a "specialist" whome does not know the trouble shooting steps and had to refer to a manual and would read directly from the manual. I go through the usual trouble shooting steps I had gone to the first time knowing that this would not do a thing. He then offered a second repair or a replacement. I decide I want a refund, but my machine being a cto unit they have to recieve approval. Thankfully I was approved for a refund and I am very glad. Sorry mbp rev a I give up, I will patiently wait for a rev b or for the 17". I feel that we have been treated like lab rats testing the new intel hardware. I must say though that apple has treated me very well each time that I have called and they have always been understanding of my situation. Buying the mbp in my case was a mistake but I hope apple will fix all of these annoying bugs for rev b.
