So I just wanted to post a little tidbit that I have noticed about build weeks and defects. My friend just received his 2.4 MBP today. The thing is flawless, as is my 2.8. I checked his serial number and his is from the same build week as mine, which is week 46. Now, I have talked to a few other folks with defects all from before week 46, including someone who was sending their week 45 MBP back for replacement. All of a sudden it seems like from the few situations that I have seen most, if not all, of the defects that were appearing seem to magically be disappearing. Just my two cents but I sure hope for everyone else out there looking to buy that this is true.
