Hello there, Tommorow is my last day to ask for a refund for my new Rmbp 15 inch. It has the samsung display LSN154YL01-A01. Unfortunately, there is a slight yellow shadow in the center of the screen. It's not really annoying but it's noticeable (My wife says it's almost invisible to her). I see it even more clearly when the computer is booting up with the grey backgound and the apple logo. Should I return this computer just for this? I know the yellow tint issue thread, people got 3-4-5 screens and all of them experienced some yellow tint issues....now, i need a computer to work with, my old one died. Are they going to ask me anything if I want a refund at the Apple store? If I decide to get a refund, should I erase everything that I put in it (music mainly?) Is there a chance of getting a better screen buying online and directly from China? Or ask for a new computer at the same Apple store? As anyone got a perfect screen after asking for replacement? Are my hopes too high? I don't want to end up with a worse computer. Thank you for your help.
