I wish I had that kind of money to throw around..
Apple Store support employees usually doesnt know much about this stuff. 99% of the time I know more than what the geniuses or any apple support people do. They probably just say yes to get you off their back.
8GB of RAM will boot with the 2.4/2.53GHz unibody mbp but I remember in the article they say only 6GB of RAM is actually utilized and if OSX tries to utilize all 8 it crashes. Theres no doubt its a limitation on the logic board.
Boy am I glad I sold my 2.53GHz unibody mbp just before the new updates hit.
when i do, i can go six. and when i need more, its almost cheaper to update to a new gen instead of blowing 1000$ on ram. 
Yes, this would be great to do, and more constructive that presuming, ala Whitefang. Though there wouldn't really be much use for 8GB's in the Macbook for users, let alone in the MBP's. We're a very select group of Mac users on here, so most people won't care or even know that the 15" MBP's have the capability to go to 8GB. I'd suspect that of all the users on our boards that could actually make use of 8GB - would take up most of the Apple users on the whole. But then, that would be presuming
A little over $1000 I think with tax/shipping. $1044 I think.
Obviously OWC is much cheaper, but I was annoyed by them because they weren't listening to exactly what I was saying.
You will save hundreds.
