Because vi was written in the days when you only had 24 (green and black, 
fixed font) lines on your console and every one was precious! If you 
have room to spare you can switch on 'show mode' which displays when 
you are in an 'insertion' mode on the bottom line.

This waste of space was one of the old arguments vi users used to 
bash emacs - it wasted 2 lines, one for the info display line and 
one for the command line - scandalous!
