Sending people to Mars would be a huge waste of resources.  Any
    exploration can be done by robots and remote control.  Almost all
    terra forming would better be done remotely *before* trying to send
    people.  People are heavy and take lots of support and you *still*
    have to send the probes and instruments.

Sure... and I agree with you, logistically it makes no sense. However where's 
the fun in sending probes... it is hard to get a dream going on the basis of 
sending a probe to Mars.... colony ships heading off to another world... now 
that is something that can fire the imagination.
Not disputing your observation at all -- and I agree on the level of reason, 
but my gut, my emotion wishes to see our species become an interplanetary space 
faring species inhabiting many moons, asteroids and worlds.
Cheers,
