[net.unix-wizards] mice vs trackballs

henry (04/06/83)

David Chin's suggestion of replacing mice with trackballs is interesting
in some ways;  unfortunately, you cannot sketch with a trackball (try
it sometime) and you can with a mouse.  Either one is fine for pointing,
but the hand-eye coordination used in drawing simply doesn't work with
a trackball.  The two are not functional equivalents, so replacing one
with the other is reasonable only in specific applications.
