hm...that statement is misleading...there's only one CPU in the die (unlike IBM's implementation of having 2 CPUs in one die) but the CPU can simultaneously handle two threads, making it appear as if you have 2 CPUs. "2 logical CPU's on a single die" is more like it :) anyway, off-topic again :P _ Philippine Linux Users Group.
