wait...even if you neeed one right now you should borrow OR go to an apple store and use some of those macbook pro from there every day until your job is done.
Think of it as the automaker every year they come out with new model, what is good is matter to them, like the flower seller says the flower always smells good, how desperate you want is what you are concerning.
