The good news is that the tc4400 is everything the tc4200 was, but better. For a start, the tc4400 ditches the original Centrino components for some far superior Centrino Duo versions: the old 1.86GHz Pentium M 750, 400MHz RAM and 915GM chipset have become a 2GHz Core Duo T2500, 667MHz DDR2 RAM and the 945GM chipset. -PC Pro
