Not that I disagree, but how would you know this?
It takes very strong magnets to "erase" the information on magnetic strips. I would be surprised if the magnets on the new iPad covers even came close to being a fraction of the required strength.
everything you mentioned is fine. However, it's all due to people specific use. If you abuse your devices, yes they will fail or degrade.
How about the NVIDIA 8600 graphics card issue? They "quality tested" those and they still wound up rotten. Also, the device cable catching on fire isn't due to "user misuse"... it's due to poor construction and insulation of the conductors.
Oxidised Alumnium cause by friction! now apply this to the ipad and that metal hinge and rub them together! returns anybody?
That is not oxidized aluminum, it is chipped paint.
what is this picture supposedly showing exactly?
The lower right of the image shows an area in which the silver paint has chipped off.
