Sorry if this was posted somewhere else, I looked but I didn't see it - anyway, is it better to buy with the educational discount + free ipod, or sign up and use the hardware discount through the ADC? This will be my first mac purchase so I don't really know what is a better deal and what comes with the student adc membership. It is just a one time fee of 99.99, right? and how much is the discount usually? I saw the page said it varies according to region, and some other things. Thanks for the help.
