Hi I'm looking to buy a new MBP within the next two weeks. I have decided between either the 15" 2.8Ghz, 7200rpm or the 17" 2.5Ghz, 7200rpm MBPs. If I were to buy the 17" model would the resell of that be at a larger loss than if i were to sell the 15" one since it an older model? I also can wait until Macworld 09 if they are going to release the new 17 inch then, but I have a feeling it won't be for some reason. If I were to buy the 15" I will definitely buy an external monitor with it. I was also wondering if any monitor would work with the new MBPs. Thanks!
