Hello everyone. I am having trouble deciding which one to get. The older Macbook Pro 2.4 GHz (middle model) is on amazon after rebate for about $16xx. While the new released base Macbook Pro 2.4 GHz is about $18xx from Mac Connection. The specs of the machines are very similar. Harddrive size is not a big deal because no matter what model i get i will be upgrading it to 320GB. Both can run 4GB of ram. The only main difference that i can tell are the new ones run cooler because the new chips are smaller, plus no multi finger gestures, and the keyboard layout is a little different. Is that it? Does the price difference justify the new features? Has anyone used both and can offer feedback. Thanks.
