For the current 15" model owners, I like to have your input. For the 2.4GHz group, what is the model number of the CPU? Is it P8600 or T8600? Same goes for the 2.53GHz and 2.8GHz group. I'm receiving input stating that the 2.4GHz is using a 25 watt processor and the others are using 35 watt processors, but on some parts, some ppl say its all 35 or all 25 watts.
