Despite those who tell you that you can't run WIndows XP acceptably fast
with less than 512MB, the right answer is that it depends on what apps
your friend runs.
This is *not* a one-size-fits-all situation. You get good performance if
the amount of RAM you have keeps you from using the page file, and that
depends on what apps you run. Most people running a typical range of
business applications find that somewhere around 256-384MB works well,
others need 512MB. Some people, particularly those doing things like
editing large photographic images, can see a performance boost by adding
even more--sometimes much more.
For most people, I find that it's not the big apps that are the problem,
it's the fact that they're running a bunch of little apps, that if they had
one or two, they'd be fine, but when they have a dozen running, the computer
starts running slow. Besides useful things like AV software, people end up
with real. quicktime, java, and similar apps in the tray, and some of them
are constantly calling home for updates. then they add on weather software,
wallpaper changers, calendar/reminder apps, search tools...the list goes on.
And that's without the spyware. And then they leave applications open, like
their mail app, a couple browser windows....
Of course, none of those are "big" applications, but if you add them
together, it's tremendous overhead.
Someone running a big app is probably *just* running that one app, and has
turned off all they eye candy and other junk to make their important program
run better.
