Hi all, I am considering a purchase of macbook pro retina. After a long time of thinking I have already made a decision about the screen size. I decided to go with 15". I was almost ready to buy it, however I/ve read some threads on apple's forum as well as on other forums like this one about screen problems: retention, bad pixels, yellow tints and purple to red tints. Are those issues still present in 2014 macbooks? It's hard to figure out if the problem still exists or is it only present in previous models. The price tag is very high to me, but I thought its because of very good screen (which i need) as well as other specs. My eyes are very picky. Sorry for my English, I hope my concerns are understandable.
