Coolest technology?

Question

What is your favourite made up but theoretically possible technology? For instance, nanites or time travel.

Answer 1

Teleportation, then there are no travel delays due to weather or mechanical difficulties.

Answer 2

hands down: iphone!

Answer 3

At the moment I am most intruiged by the theory of an anti-gravity machine...

Mostly so because of the recent theories that gravity, like light, has material properties...and as such can be manipulated.  It's exciting to think that something that negates gravity can be created.

My favorite theoretical technology of all time would be that of teleportation though...I just don't think we are anywhere close and so it's not as exciting
