Mike, 

I have seen syn floods of both types (targeting a single port and
targeting all/many ports). I am not sure why an attacker would target
all ports. There may be a way to consume resources of certain OSes in
this manner, it may just be a blatant bandwidth attack, or it could even
be poor execution of a DoS attack (ie broken code).
