I also got my Macbook Pro Retina the day it was released....after 1 month Apple did replace it (Thank you very much) due to bad clusters detected in the SSD drive. Now I have the dead pixel issue on the new device. A dead pixel very visible with a full black background on the bottom half way across.
I too agree on the comment, "If you don't have the Apple Care 3 year coverage, GET IT!! You'd be mad not to" - I have it and am reassured this will be resolved without issue with a replacement. I also have the 16 Gig ram and larger SSD so appreciate the customer care experience comments you made.
By the way, one (easy, cheep, sure and reproducible) way to use "a vendor" test for bad clusters in case you were wondering, is to install windows temporarily, give the boot camp partition the largest available fee space chunk available.
Then in (windows 7) right click the Start button, click "open windows explorer", then in the open explorer window, right lick the "BOOTCAMP C:" and select the "properties" menu item.
Click the "Tools" tab, and click the "Check Now" to run the built-in disk check.
Check the second "Scan for and attempt recovery of bad sectors" Option. Click Start.
The program will tell you when you reboot the test will be run, so do a reboot and watch the test.
Be ready to take a contemporaneous camera picture of any revealed bad sectors. Errors (if any are findable) will show up before the test finishes, but you have to snap the picture before the program finishes as the test will restart the machine when complete.
This is a good test to run as the running corruption of a bad sectors on an SSD drive will result in what can be described as a wandering/roving data corruption due to the way SSD's manage files (and fail to verify when they move file around) and move files around on the drive for optimization. Eventually the error or no error will be detected when configuration files which are not suppose to change in OSX happen to drop onto the bad sector on the SSD and you end up with smoking OSX ring 0 soup.
If I had to do it again, I'd show the Apple store Genius the screen shots First and then explain where they came from second. When they heard windows first they immediately dropped into a suspicion of the other vendor emotional condition. Which lasted until they looked at the camera picture (of the bad sectors) which confirmed the issue.
No one but a fool (world is full of them) would question that that little bit of windows, the disk check in windows 7 which evolved from chkdsk is probably ok as it has not had reproducible technical reporting issues of false positives for over 15+ years.(which should be good enough.
But trust me, a picture of the issue will work better than a thousand words that might inadvertently inspiring an anti windows bias(it could happen in an Apple store):) Don't even mention windows unless they ask.
To do this same test in OSX you need to roll out cash for an advanced disk diagnostic tool in the range of 60-120 USD. No free or vendor tool exists which will detect bad sectors on the SSD according the Genius SME at my local Apple store.
Apples been very good if not fantastic in device support, I have no concern it will be resolved quickly and well.
Best of luck and thanks.
