Lets see... where to start.
Ok I purchased the Penryn 15" MBP 2.5GHz, as listed in my sig last tuesday. Didn't have that much time to play with it due to work... but when my weekend rolled around, got to play with it and install software. Well... I noticed that the right side fan was buzzing pretty loudly, while the left side was silent. (Running at same RPMs) If the system was under heavy use, the fan buzz noise goes up in direct relation to how fast the fan spins. I decided to turn off the MBP and leave it off for the night, next day when I turned it on, right side fan buzz was still there and rather easy to notice even when the system was just booting up.
(However no yellow hue/tint on LCD)
Decided this morning to take it back to the Apple store to exchange. They turned it on to listen to the buzz sound and it checked out. So they gave me a new MBP... which I subsequently took home to give it a whirl.
To my dismay, when at home...
fan noise still there
AND yellow tint/hue on the bottom 1/3 of the screen.

I rubbed my eyes a few times and kept looking. Then decided to take it to a pitch black room to look again. Still there, decided to calibrate the screen. After doing so, the yellow tint looked even more noticeable... ugh!
Time to go exchange yet again! This time though the manager helped me. He was very polite and I told him the issues and that I just had it exchanged earlier today too... lol. He took a look at it and said yeah he could see the yellow tint and excused himself to take the MBP to the back where the geniuses could take a look as well. Evidently since its a new release (update) of the MBP, I was one of the first customers to bring it back with problems and he wanted to show it to the geniuses.
Subsequently he brought out a new MBP to exchange and asked if I'd like to open it up in the store and take a look at it to make sure it did not have any issues. That was very nice of him to offer without me asking and I gladly took him up on it. Spent I think around 10 minutes inspecting the system out and it checked out perfect. No yellow hue/tint and the fan noise while still there, much more quiet. No where near as noticeable as the prior two had. Before leaving, I thanked him for his help.
Barring any problems, this one is a keeper! 3rd time was the charm.
