check out dpreview.com ... you'll probably have to choose between "won't be too much large" and "with some profesionnal features"
Canon is my brand of choice personnaly but i have to admit that i'm not that familiar with point n shoot cameras.
I have an EOS digital rebel myself. The body isn't that big but it's still big and it can weight quite a bit depending which lens you have.
If you're looking for a not too large cam you'll probably have to go with a non SLR camera with a fixed lens.
This Canon Point n Shoot looks good:
