Wow... You're very lucky! Could you tell me why they upgraded your flash drive? Is it because they don't have any 128GB in stock? My friend's MacBook Air 2012 128GB have a samilar problem as you, will take it to a authorized store to get it check and replace. Hopefully he can get an upgrade too![]()
I have no idea what the reason was. I assumed it was because it was because the replacement was so far backordered. I didn't complain or demand anything special. All I wanted was my laptop back. I think providing the upgrade was the right thing to do given the circumstances. I purchased AppleCare as well, so in the end Apple has still made non-negligable profit from me.
