I actually should clarify that the only reason my dad has to get a Dell over a Macbook now is that he is a prefered customer and can get a great leasing rate apparently. But with Apple we have not purchased a Macbook from or any computer for that matter so we would have to pay it all up front. He can just call dell and order my laptop with no issues. In which case I guess im stuck. I just really want a Macbook over another Windows based computer.
I'm confused; is the computer for you or your dad?
If it's for you, and you're in college, the $100-200 difference in the macbook now is nothing compared to the thousands you'll be paying in school fees and books. Compared to the time you'll save not having to troubleshoot, I'd say it's worth it over 4 years. Not to mention the fact that you'll save $100 on a printer (which you'll need) if you buy from Apple.
If the computer is for your dad, why is he taking out a loan for it? Unless he's going to be getting 0% financing, a loan on a computer is a loser's bet. In addition to that, if it is for your dad, then the best way to get him to buy a macbook would be to let him sit down with one and play with it at an Apple Store. Do this, and you'll find that he'll be quite ready to switch
