What an obscenely presumptuous statement. That's like saying "long-sleeved shirts are the only practical clothing ever conceived."
Not really. Any time machine that isn't also a space ship or can guarantee it lands on Earth in another time period will kill its occupants. Very few time machines actually have this ability, but with the TARDIS it's built into the name. And since it predates most other space travelling time machines it gets the credit for being the first.
You're neglecting that gravity bends spacetime. Any old time machine can and will be affected by gravitational forces past, present and future, ie dumping the vessel back in the same geographical locale it left from. More or less. Continental drift could pose a problem.
