What is the smallest all-in-one printer available?

I am looking for an all-in-one printer that has a small footprint and generally takes up a small amount of space on my desk. I currently have an HP PSC 1210 which has dimensions of 16.8 x 10.2 x 6.7. I am looking for something that is the same size or smaller even! Functions that I am interested in are scanning, copying, and printing and I would prefer a flatbed.
