Well, it only took about two weeks to get my Macbook serviced, send it back for a new case after they destroyed the first, and have it returned.
At this point, I guess I'm happy with the results. The condition of my new casing still isn't as good as my first. There are a couple of good sized scratches and it's a bit warped in one spot. But, I'm going to have to give up and declare Applecare the winner in this game of wills. I just don't have it in me to spend another week without my computer. Really, at this point, the flaws are so small it wouldn't make much sense to complain. Believe me, if it looked as bad as it did before I sent it back, I'd have no problem complaining again, but this just isn't worth the trouble.
They did their best, which isn't as good as I would like, but I guess it's good enough.
