The reliability of these products was sacrificed before a golden idol of Jony Ive on the altar of Thin. I find it interesting that this program is announced more or less at the same time he announced his formal retirement from Apple.

This was my experience. My battery was having issues and indicating service was needed, but they refused to only replace the top case since they claimed there was a "logic board failure" that caused my A and S keys to skip and repeat.

Not sure where they came up with that conclusion originally.
