i removed the map program that was preinstalled, i use maemo mapper anyway. it was 8mb.
pengupop or whatever that crappy game was, i think it was smaller, but i removed it just the same because i didn't like it.
a few other crappy games.
there was another program i removed that was 8mb, but now i can't remember what it was.

i thought it might have been a space issue when i tried to set a bookmark for this thread so i could come back to it easily and it told me there was insufficient space. i checked and my rootfs was 98% full.
