Do you find Tiger to be memory hungry?

D'Arcy Norman posts about Tiger's memory usage on his blog, noting, "It seems as though MacOSX 10.4 is a wee bit memory hungry My Powerbook has a gig of RAM, and Ive been stuck in VM thrash hell for several minutes on a couple of occasions (which hadnt happened at all since I upgraded to 1GB from 256MB while running 10.3)."

I've noticed similar behavior on my Powerbook G4 with 1.25GBs of RAM, but I've not heard the same complaints from my G5 Tiger-weilding friends. I wonder if there is a difference in RAM usage betweed G4s and G5s. Please weigh in in the comments with your experiences, TUAW readers: Is Tiger eating too much of your memory since the upgrade?

Make sure you tell us your system specs so we can try to see some sort of pattern (if there is one).
