I got it as an open-box at Best Buy so after my RZ certs and tax, it was "only" about $720. Figure selling off her white MB would be about a wash then.
No kidding though! When she almost immediately said she didn't want it, I was like, what the hell? Now, I suppose if my Dad (who's 64) bought me a nice Windows laptop for some reason and he thought he was being really great about it, I'd give a nicer reaction, even though that Windows laptop doesn't at all suit my needs vs my MBP.
Good thing you didn't give her one of those, she might of smashed it to pieces. (just kidding)
BTW, get used to it. Soon she will be expecting the bucks with the same sort of reactions. Ain't gonna get cheaper; (unless you fake your own death and make a clean break NOW)
