I know what Centrino's do. Their new features and such. What I dont understand as of yet is why the smaller sized chips. The laptops I am noticing on the various websites (ie. Dell, Toshiba, ect..)are 1.2GHz through 2.0GHz, small by the latest p4 chips. Are the benchmrks of these new chips faster? Looking for benchmark tests and havent found any yet. Thanks
