I don't have either one, but I know a lot of NAM'ers do, so I figured I'd help pass along the news as reported by Daily Tech.

Here are some of the notable addition/fixes with the Nikon D40 1.1 update:

• The product will be "Certified for Windows Vista".
• Support for the new USB Media Transfer Protocol (MTP) has been added.
• An issue that caused the ISO auto feature to be disabled, when a two-button reset operation was performed with ISO sensitivity set to any option other than ISO 200, has been resolved.
• Errors in English, Polish, Swedish, and Traditional Chinese menus have been corrected.

Likewise, the D80 1.0.1 update adds a few fixes of its own:

• The electronic analog exposure display will be displayed in the viewfinder when the brightness of the subject exceeds the range that can be controlled by the camera, whether too bright or too dark, in the following shooting modes:
• Shutter-priority auto (S) or Aperture-priority auto (A) exposure modes with the built-in flash up
• Programmed auto (P) exposure mode
• Effects of processing performed when the Long exp. NR item in the shooting menu is enabled have been improved.
• When attempting to edit images, which had already been edited using a computer, with options in the D80’s retouch menu, the camera sometimes froze. Therefore, images that have been edited using a computer can no longer be edited using the camera.
  Errors in English, Polish, Swedish, and Traditional Chinese menus have been corrected.
