I figured I'd vent in a place where like minded people can appreciate my frustration... I purchased a Retina MBP on day one, stock 2.6 GHz / 8 GB. It has the LG screen but all was fine. Then, out of no where, the image retention started, and very bad. I called Apple Support, they set me up for an appointment to take it in, and they swapped it for me for a brand new machine. This time, It has the Samsung screen. Flawless, no dead pixels, bright. perfect. I was VERY happy. That was until I plugged in my iPhone, and the left USB port didn't work. Tried my iPad too. iPhone 5, iPhone 4S, and iPad3. Nothing worked. Dead port. I made another appointment the next day. They looked at it, and offered me either another new machine, or a repair. Since I got the screen I was happy with, I chose repair. They ordered the part, and I went home. 2 days later, I went back when the part was in. I waited 2 hours, and off I went home with the port repaired. I was happy... Until I got home and plugged in my power adapter, and no light turned on. It wasn't charging the battery. SO, I made an appointment for later the SAME day. I went in, they took it in back, and re-seated everything, and it worked. I waited almost another 2 hours, for the second time in one day. We checked every single port on the mac before I left, and everything worked. I was happy... Until I got home and realized the backlit keyboard doesn't work. I never saw it in the brightly lit store, and didn't think to check it. I have yet ANOTHER appointment for tomorrow morning. My frustration level is through the roof. I didn't want to take the chance of getting another LG screen, so I opted to take repairs on a BRAND new MacBook Retina. In retrospect, I should have chanced a new one, but with my strong of luck, I'd lose the Samsung. Ugh... Just some advice from me, if you take in a repair, check EVERYTHING before you leave. Every port, power adapter, and backlight. Speakers, fans... I'm fairly certain something isn't seated properly again. Hopefully tomorrow, this will all be good and fixed.
