So... one more note.
After buying my SD1100 in early December 2008, I connected the usb cable one time on each of 3 different computers. Not being super impressed with Canons software, I proceeded to install CHDK. Late in December, I tried to connect with the usb cable again and on all three computers, windows XP said the drivers were corrupt and would not work. Hmmm.
Yesterday, I went after this problem and all it took was remove/reinstall of the drivers and the interface began working. I don't know if CHDK did anything; it all works now.
So a moment ago, I tried Canon Utilities CameraWindow DC and sure enough, there is an icon in the upper right called SET. Clicking on that allows me to type in a name that gets sent to the camera and ends up in each and every photos EXIF data.
And I notice that transferring photos by usb is about 5 or 6 times faster than pulling the SD card, putting it into the destination computer and copying across.
So all is good!
