Gosh Larrabee, I'm really surprised you got treated so poorly. It's always tough for me to go to an Apple store because they have their heads so far up their own butts. Every time I hear the word "genius" I start getting angry and want to grab them by their little pony tails and start strangling. apple, here's your first clue: if you call yourself a genius, you are probably not!
Anyway, I am baffled they just won't replace your computer, especially after breaking it. I can't believe they are going to switch out parts, what a waste of time. They must be planning to switch your hard disk into a new or refurbished model.
Did you get pictures of the damage?
Did you actually cry in the Apple store and they didn't give you whatever you wanted? Unbelievable!
