    A compelling argument? Launch UT2004 and some applications in the background.
    They'll get swapped out. Shock horror when you wait x seconds before system
    gets responsive and applications are swapped in. (especially the new manual
    option helps)

    Same applies to any large compile. (KDE with --enable-final springs to mind,
    but Firefox should also be large enough)
    Even 0,5G of memory is not enough for those and a few apps.

    Another boon is retaining swapped-out data.
    Saves a lot of time when I keep large applications in background and only use
    them sporadically. (OpenOffice springs to mind)
