Having finally received my shiny new MBP (15.4" 2.8ghz CTO) yesterday I was rather disappointed when I noticed 2 issues: 1 - The screen is really yellow (even after all attempts to calibrate) as compared to the 2.53ghz model I had previously. 2 - The machine randomly makes *really* annoying fan/vibration noises. This is regardless of processor utilisation or fan speed - it seems to depend on how you hold it! I contact Apple Sales by phone this afternoon, and although they had nothing to say about the yellow display, they acknowledged they've had complaints about the fan noise. Here's the important bit: There are 3 options... 1. Applecare via a retail store (which means giving them your machine and waiting for them to get parts and repair it) 2. You return it and wait for a replacement (approx 2 weeks at present) 3. They ship you a replacement and THEN you return the faulty one You need to ask for the third option as they probably won't offer it. They'll ask you to sign a waiver promising to return the faulty machine within 5 days of receiving the replacement. The form requires your credit card details and authorises them to charge you if not returned. The replacement is ordered once they have the waiver back. Just thought this might be of use to those of you having problems with your lovely new machine. Good luck!
