Since I access your site every so often, I'd say you are an educator of sorts, so in that respect, using educational pricing, the difference between the white high-end Macbook and the low-end Macbook Pro is $650 plus taxes. You get the bigger, newer screen, a minimum $100 Ram upgrade, the latest processing power, the latest and much, much better video card, and a whole bunch of other things too technical for me to understand.
