Can you recommend a small digital camera?

I have a great DSLR camera but I seem to take more pictures with my iPhone because it’s always with me.

I would like to get a small (as small as possible!) digital camera so I can always keep it with me to take pictures.

For a brief moment, I thought about getting the Canon G9 which is a fantastic DSLR alternative but is way too big for my needs. If possible, I would like to get something smaller than the Canon ELPH or SD series.

Do you have a recommendation for such a digital camera? A friend recommended the Casio Exilim series but before getting one, I thought I would tap the collective and ask my friendly fluther-buddies.

P.S. You can see my awesome-tastic pictures (and leave a comment or two) at http://www.flickr.com/photos/atharkhan/
