Perhaps the bigger disadvantage is Mars's lack of a magnetic field to deflect cosmic rays, which will result in radiation poisoning for anyone attempting to reside on the surface. A Mars colony looks like a foxhole with an antenna. Not too sexy. To say that some terraforming is needed is an understatement.

That's nothing we CAN fix though - not without geoengineering, we most likely would be better off by generating that field ourselves somehow. But yeah, I DID forget about the cosmic rays.
