I watched JUMPER the other day...  

Teleportation is a very interesting ability for a superhero sort of movie. Superstrength, superspeed, eye-blasts, or other such stuff seems very comic-book fantasy. Not everyone can get into that. But teleporation.. that's a simple dream we see in movies like the "Fly" or "Star Trek." As simple as wishing you could travel without the tedium of flying, driving, or even walking. Who on a long car trip hasn't thought how wonderful it would be to just teleport there in the blink of an eye.

What would you do with the gift of teleporation? Well, but things, little things.. all sorts of neat stuff to imagine. Imagine you are moving furniture at the office and you can just 'zip' lots of heavy stuff over where it needs to go while people aren't watching.

What about zipping off to watch a bit of a movie during a slow part of your day?

Then there comes the larger daydreams, visiting unusual places -- teleporting to Spain, Ireland, Greece, Russia..

Then even more fun, what else can you teleport? Could you teleport to the erupting volcano in Hawaii and then zip a rain of hot lava down on some nation supporting terrorists? Oh, look "God" is angry and dropping lava on you for your hate-mongering?

Just.. so many things to imagine. (Perhaps the lava-trick isn't very wise, but funny to think about.)

Eventually, I guess you'd have to start teleporting into places where people are purifying weapons-grade uranium and send all their effort deep into the sun. That's the sad part of daydreaming about super powers.. the burden of having such a 'gift' would eventually pretty much require you to sacrifice your life for the common good. The 'gift' would become a curse, in a way, I think.

Ohs, I am about to make this last reponse as the best. Sadly you put it under the first response.
