The Apple AirPower mat comes to mind although there are rumors they haven't abandoned the effort completely. Butterfly keyboard seems to finally be acknowledged as a bad idea and took several years to get there.

The next Macbook refresh will be interesting as there are rumors they are bring back several I/O ports that were removed when switching to all USB-C.

I agree with your overall point, just some things that came to mind when reading your question.

ah yes, the butterfly keyboard. i must have blocked that from my mind after the horror it was. although, they didn't admit anything on that one. that was just another "you're holding it wrong" silent revision that was then touted as a new feature (rather than oops we fucked up).

The trashcan MacPro is still the only mea culpa I am aware of them actually owning the mistake.

The Airpower whatever was never really released as a product though, so it is a strange category. New question, is the Airpower whatever the only product offically announced on the big stage to never be released?

Do you really care what they "admit"? I thought you were worried about innocent people being framed. Obviously if a way to frame people gets widespread, Apple will stop it. They don't want that publicity.

You clearly have me confused with someone else, as I never mentioned anything about innocent people being framed.

With Apple, nothing is "obvious".

The comment above that I responded to seemed to talk about that. But in any case, I for one don't care what Apple admits.

But I am certain they will not want all the bad publicity that would come if the system was widely abused, if you worry about that. That much is actually "obvious", they are not stupid.
