Our family actually does the opposite of what seems to be the trend. We have a digital/analog video camera. What I have done, and plan to do on this trip, is just let the video camera run on the tape mode. Then, I plug it into the TV (so I can see better!) and "clip" the pictures I want onto the digital memory stick. The video quality on ours is better than the digital picture mode, unless it's set into super fine (which REALLY limits the amount you can put on a memory stick), so I just wait to clip the digital pictures into the high quality mode when I'm at my computer and can download them.
Our video camera is only slightly smaller than the 35 mm camera that we had been using. It actually fits into the same bag, so we just leave the 35mm at home, and push one button and let it run!
But I do agree that it's whatever works for you. In your situation, where you'd be borrowing one from someone else, I'd agree it's probably not worth it. It took quite a bit of playing around with ours before I figured out how to do what I described above.
Have fun!!
