I have been looking to purchase a MacBook Pro since the Santa Rosa refresh having been a PC user all my life. Unfortuneatley I have not managed to save enough money for the 2.4GHX 15" and would like a Laptop before I return to University in the Beginning of October. My sister recently purchased a Base model MacBook and it seems to be a splendid machine that would tide me over till the next MacBook Pro refresh. I am wondering how much money I would likely be able to recieve for selling the base model Macbook at that time? I do a lot of graphic and web design in my spare time so the extra screen size and dedicated graphics would be important to me. Many thanks.
