Throw a fit! How dare they try to save a few bucks. If they don't run out and get you a Mac right this very minute then they don't care about you!
You need to show them who's boss. Find their credit cards, and sneak down to the Apple Store and get what you want! Hide the Mac until the bill arrives, which will be next month, and by then you won't worry about what they think.
I should be a family counselor.
Legal Disclaimer: I'm just kidding! Do not take me seriously, or ever believe anything I say for that matter, as I am probably lying, except right now, I'm telling the truth, just this once. Be grateful to your parents for trying to do their best for you. Enjoy your brand new Toshiba, and always remember that it was one of the many wonderful things they've given you. There, I've said something nice.
I still should be a family counselor, don't you think?
