My wife got a new laptop for Christmas and we’ve been suffering ever since trying to figure out how to keep our photos in sync. Usually one or the other computer is not turned on, or the DHCP server has changed the IP address of the desktop or some stupid thing. I found an article today describing www.foldershare.com. They have a little application that sits in your system tray and synchronizes selected files among all the computers you authorize. It does it all in the background and it does it quickly.
