I'v just got a new mac, with 30G hdd, preinstalled with OS, iLife, iWork trial, etc. It's good but consumed much of the hdd space (about 1/2 of my hdd). I've removed certain applications, like the msoffice trial, some accompanied games, the world atlas, to free some space (~2-3G). I remember i've tried to clean install tiger on another mac. The os (+xocde & X11) only took ~5G or a little bit more! Can anyone suggest ways to make a mac thinner? thank you.
