Centrino is a marketing scheme of Intel which means that the laptop comes with the banias processor (1M of L2 cache) and a built in wireless thing...
yeah... well that's how i understood it at least...
so something that has the p4m + wireless wouldn't be called centrino...
or even a p3m + wireless... it has to be the banias processor + wireless
if its just the processor w/o wireless then it's not called "centrino".... yeah kind of weird....
