One of my accounting textbooks was talking about statistical analysis using computers, and had this photo.  I had no choice but to laugh, take a picture, and upload it here for no one’s enjoyment.  Computers one day may be in many homes!

Benefits: can display several shades of green to help visually represent data, business records can be saved on floppy disks that hold over an entire megabyte each.
Downsides: very costly and not realistic for home use, internet will not be available for about 10 years.
