yeah, get the ibook. i would try to save up a bit more and get the combo drive. since workign at an apple resller, i would reccomend going the apple loan route. use the same as cash deal and pay selection over 5 years. in your case you will actually pay eveything before then. pay a thousand and with a job if you hve one pay off the other 4 hundred. they nice thing about the 5 year plan you only have to pay 20 dollars a month. and since there is no penalty for prepayment youll get everything taken care of, and if you take care of everything within 180 days you wont have to pay any interest. that is the way i would reccomend if you are short on cash for the upper model. plus with the combo model you get the burner, dvd, and a better video card. hope i was some help.
