What´s the diference betwin a Core 2 Duo 2.4 for desktop and a Core 2 Duo at 2.4 for laptop (like the ones on the iMac). I understand the laptop processors are designed to save energy and produce less heat. But what´s the diference in performance? If there is one. Aren´t those 2 running at the same speed? If they are similar in performance I don´t understand where are people complaining about laptop processors the iMac. If they are not similar, how big is the diference? I really lack of knowlege in this area, and need some help from people who REALLY know this. Thanks.
