Oh, nothing against you personally. And yes, the managers are very well informed (in most cases, I have run into some...less intelligent persons).
But it was just that one part that got me taking a second look. No one at Apple is sly enough to get you to buy a new part or machine, they just don't know.
Short story. Waiting at the Genius bar and a person comes and ask the Genius about a replacement "duck head" the two pronged piece for your MB power adaptor.
The Genius tells her they don't replace them, and that she could get a new power adaptor for $80. I told her to call Apple Care and have them send her one for $10.... or just use the extension cord. The Genius just didn't know about that service.
funny mine was a little loose so i went to the apple store and the "genius" gave me a new one on the spot today
