I think one of the advantages/disadvantages should be immediately 
obvious, you need an 80 ft plus tower to put up a 40 meter half wave 
vertical dipole.  If you do put it on a tower, it will no longer be just 
a vertical dipole, it will interact with the tower.  If you have an 80 
ft tower I can think of many better antennas to put on it.

If you have an 80 ft tree, you could put up a half wave sloping dipole 
that would beat a vertical  in some directions.  If you have two 80 ft 
trees, you could put up a horizontal dipole that would beat the half 
sloper and the vertical.
