basically you get 2 processors in one package. There are a couple of
things that result in it not being twice as fast. One, there is overhead
that causes a little processor use because they have to share resources
and two, the work has to be assigned or parceled out. In general use,
you would see anything from about 120 to 180% of a single processor of
the given speed. As for the hard drive, lets say you replace the 4200
with a 7200 rpm. You won't be changing the burst speed(read from cache)
but you may pick up the hardware data transfer rate maybe 50-60 percent.
So outlook takes 2 seconds to load instead of 3. My personal choice
would be to continue using the current laptop as is for about a year and
then in middle of next year when the Vista installs are all sorted out
by the vendors, pick up a new one with all the bells and whistles.
