Yes, I have them everywhere too...car, gym bag, bathroom, next to bed, under bed, kitchen. The worse is when I loose one, print it again, make notes all over it, find the old one and then have to compile all the scribbles onto one!
I think the idea with using EndNote as an electonic store with P for printed ones is a good idea, I think I will go that route and give up my guilt about the paper and ink, oh, and filling up the house
