The race is on to produce four-core processors for PCs. Intel, which is readying a bevy of dual-core chips for release in systems in the next month, is already plotting a move to quad cores, which some reports have said could come as soon as early 2007. AMD has already discussed a plan to begin offering a family of four-core chips in 2007, whereas Intel has only hinted about a four- core server chip thus far.

Yes, at some point or another. Let's say you have one resource hungry process that keeps one cpu busy, and a bunch of little processes that keep the second cpu busy 1/10 of the time. If the big process properly supported multiprocessing, both cpus would be busy all the time (minus communication overhead, which approaches zero if the multiprocessing support is "done right").

Most of those processes are asleep. A better figure is:
$uptime
0:05 up 11:56, 2 users, load averages: 0.19 0.08 0.03
Note the loadavg of less than 1.0.
