I finally made my choice and I will be buying a top end 15 inch macbook pro. I am concerned about yellow tinting that seems to be in all screen and hopefully mine won't be that noticeable and with the cracking issue also. Is there a better chance of having a problem free macbook pro ordering online and the computer coming from China or just go in an apple store and get one that has been manufactured like 20 weeks ago. Is this overkill for my needs. I do surf the web and do photo editing (photoshop, lightroom 5 etc.) as an hobby. I plan to buy a 4k display next year. I don't really game. Should I be better with Iris pro only? I want the computer to be future proofed. It will be mainly used in clamshell mode around 60% of the time. I don't have any other computer only my wife's 2012 macbook air. I want to keep this computer 3-4 years. thank you very much.
