Jeg tror at hvis du opgraderer maskinens hukommelse (det vil sige erstatter det nuværende hukommelsesmodul med et 256 MB modul, vil du få en sjovere Linux eller alternativt en sjovere Windows.
Computeren vil ikke være alt for langsom med mere hukommelse, hvis du holder dig fra at afspille video, køre Compiz i Linux (en bedre end Vista 3D grafisk lir brugergænseflade), og ligende.
Bemærk iøvrigt at det kan være at du har købt din laptop kun med den hukommelse som er loddet fast på bærbarens bundkort, det vil sige uden et hukommelsesmodul. (Kig i listen "Memory (standard) A21m/p" og efter teksten "on the system board").
