I have had my 15-inch C2D MBP for 4 days now. Although I am happy with it, I was having a hard time deciding between the 15 or 17 before I bought. After using the 15, I think I should have gone with the 17. Any chance I can "trade up" and avoid the restocking fee or am I out of luck? I bought it at an Apple Store so, I assume I will have to handle this there as well or can I deal with Apple direct? Thanks.
