Interesting update on my end.
I put my old SSD in and got my laptop re-diagnosed yesterday (Monday). Unfortunately they could not simply refund the $200 I spent on my OWC drive, but they agreed to replace my old SSD.
Today I got a call from one of the employees at my local Apple store, and she informed me that the company is facing an extreme shortage of these replacement SSDs. As a result, they've decided to replace my entire laptop free of charge. I was told I could do it tomorrow (Wednesday), but reminded her that my MBA was CTO (8 gb RAM) so she said I can come in Friday and they'll replace it then.
So overall, I still wish this whole thing never happened but I'm happy that I'll be getting a new MBA as a result, missing all the dings, dirt, and light-bleed my current one has. I'm assuming it's an identical mid-2012 model, but I'm crossing my fingers (with very low expectations) that since it was CTO they might need to replace it with a newer one. A man can wish.
Will be interesting to see if people have situations similar to mine. It puzzles me why they wouldn't just remove the SSDs from said laptop they're replacing mine with; maybe it is some sort of insurance or tax write-off issue. Who knows.
