I use a Sony Mavica, the FD88. It uses 3.5" floppies.
You can take pics, view them on any computer or give the floppy to someone else.
Pic quality is good enough for computer use.
Resolution can be changed for larger pics, smaller pics, etc.
Micro and Macro capabilities - both pretty good.
You can duplicate the floppies in the field using the camera.
The camera is physically larger than non floppy cameras.
Uses a lot of electricity because the disk drive has to be powered from the battery too.
You have to carry a lot of blank floppies.
See attached .jpg demo. Total time - less than 5 minutes. That includes image editing, finding the camera, finding a disk, answering the phone etc.
If you carry an extra charged battery and plenty of floppy disks, the versatility of the Sony outweighs the benefits of the smaller cameras. I can go into my shop, take a pic and send it around the world in a matter of minutes.
