Syncing of photos across multiple computers in Windows Live photo gallery is amazing. Previously my workflow in photo management was so broken and cumbersome as I have multiple machines where I will download and edit photos and will have to manually keep track which photos I edited on which machine to manually overwrite on other machines (and I would frequently screw up). With Windows Live Photo gallery I just import on one machine and let the magic of Live sync work. Even if I edit it will keep the photos synced.. Download it from http://download.live.com/photogallery if you have not done so already..
