We got a Casio 30 digital camera when it was the cheapest digicam last
year.  Now there are more cheap ones, and the technology is improving.

It's better than Poloroid for grabbing a snapshot "now," and it's great
for dropping in images for design concepts and presentations. I've used
the images as a starting sketch in developing designs in paint and draw
programs. The Casio computer connection is straightforward. I've used it
on both mac and PC. I did have a problem with System 7.6, but restarting
with mac Extensions off allowed it to work.
