i feel confused seeing different answers. some say it is wasted, some say
it
is not.
i heard that the rest of RAM is used for hardware addressing purposes. can
someone clearify on that please?

HP says my notebook can run 64bit vista, but i dont think i'd spend time
to
change it fearing that something may not work.

After installing SP1 on Vista, the system properties report that I have

RAM installed, which is true.
However it seems that from the Task Manager, it only can handle up to 3
Gb
RAM. So is the other 1Gb wasted? Or is it actually in use for other
invisible
purposes?

NO it is NOT wasted, yes it is available, just not reported.



Install Vista 64 only if you have a requirement to use MORE than 4gb. Not
all hardware devices have 64bit drivers written for them. Also, some 32bit
programs do not work as well as they might..
