You remember these right?  Flash cubes?  If you're like me, you certainly don't miss these.  It was one and done after using them on your camera for each photogragh taken that needed a flash to illuminate the image.  I remember having to carry a bunch of these around, along with my large camera.  I don't know anyone who isn't grateful for cameras becoming digital so that you never again have to point, click, and hope for the best.  You were lucky on a 24 exposure roll of film if 8 pictures came out good.  Then of course if the photo wasn't overexposed or too dark, then someone certainly had their eyes closed.  Yes, we all love digital cameras!
