hi all, so after going through 5 exchanges (some of you might've seen my other thread), due to pretty much real bad luck and encountering every single issue known here (image burn/ghosting, yellow blotches on screen, fragile display, freezing).. i almost gave up.. decided to just return my last one completely. but as i was about to leave the apple store.. i decided that i'm a sucker for punishment, and i'm not gonna give up yet.. one more try... so i end up going for my 6th try at this, but this time.. i wondered if getting the higher tier 13" 2.6/512gb configuration would break my bad luck streak (i had the 2.4 8/256gb configuration before).. i figured.. more expensive.. maybe apple assigned more careful people to assemble these and pick out parts from a better bin..? wishful thinking, but i truly hoped so... apple gave me a pretty good discount, and in addition.. let me pick out free stuff worth up to $150 for all my troubles. so getting the more expensive configuration actually ended up being a bit less expensive for me. i give apple customer service credit for being good during my ordeal. anyway.. my new one now has a serial # ending in 01. all 5 of my previous bad rMBP's had serial #'s ending in 00. i'm not gonna say that this one is perfect, as i've jinxed myself before by saying that.. but let's just say that this one is a keeper so far. what i noticed first was that the keyboard keys are exactly like my 2011 Air's (which i loved).. where it has a bit of a concave shape to it, has a more matte coating, and a bit more travel than all 5 of the previous ones i've returned. so i wonder if this is from a newer batch? do any of you have one with a serial # ending in 01 as well? if so, what is your configuration, and do you have any issues with it?
