How much ram should be free while idle?

[Looon]

I just got my 13in mbp a couple days ago and I've been watching the activity monitor since one of the reasons I got a pro was for the extra ram over the macbook. Mine seems to only have about 2.08 free while I have nothing running except whatever it came with since I haven't installed anything yet. This seems a little low considering the regular macbooks only come with 2gb how could they even run snow leopard? Am I missing something about reading the activity monitor or is there something I can do to free up more ram or is this just normal?

hmmm it does seem a little boged down to me, i have 4 gb of ram (ddr2) and i have 2 gb free whule i have mail, iphoto safari, and finder open, when i get diabo 2 running and itunes it drops to about 700 mb of ram free, its surprising when you start seeing what it actually uses to run simple things >_<

If "free" and "inactive" memory combined are over 2 GB's, don't see an issue?

Do you have iFreeMem installed? If not, get it.
