Yes I admit that was kind of stupid of asking the 50gb difference. What i meant to ask was the difference between a 7200 rpm and 5400 rpm.
I was thinking of buying a refurbished but since Apple has the student program thing the cost of the MBP would only be 2300 plus a $300 rebate and a $300 iPod Touch. Which, in a way, lowers the price down to $1700.
