ASM, DivX, Flip4Mac WMV, FruitMenu (can probably get rid of this), GeekTool (this too), GnuPG (and this... maybe), Growl, MenuMeters (haven't ever touched this), Perian

ASM... appears to not even load, I can probably chuck this.
It goes without saying that DivX isn't a <em>system</em> preference, it doesn't need to be there, but oh well.
Flip4Mac is very helpful.
FruitMenu... I don't even remember what the crap that is. Something about Menu Skinning or something? I've never touched it, probably got it at some tweakers recommendation. And apparently it doesn't work on Leopard anyways, ha. Total trash.
GeekTool looked interesting, but I haven't found a personal use for it.
I prefer command line interfaces to GnuPG (and SVN, but that's not in my sysprefs :P, so we don't have a problem).
Growl is <3
I used MenuMeters once, but I really don't care to continue to look at those stats, so they've long since been disabled.
Perian is also insanely helpful. But, if I have it, can't I kick Flip4Mac to the curb? Hmm, maybe not. I guess it gets to stay, <em>for now</em>.

So I nuked ASM, guess I got used to knowing my active App without the cute icon in the GMB, and FruitMenu, gooooooooooood riddance.
