Trek communicators from TOS. Taken a look at the flip cell phones?
PADDS - tablet PCs. Also useful for displaying charts and such while
in the cockpit (just to keep this on an aviation topic)
Back to TOS, remember the data cards that Spock and Uhura kept loading
into the computer? Just like 3.5 floppy disks (talk about two-way
nostalgia!)
FTL - Hawking claims he's working on it.
Medical scanners - maybe not as sophisticated yet, but it'll happen.

Of course we're still working out the bugs on transporters....

A number of current and retired members of the US Astronaut corps have
admitted to being motivated by Trek when young.




Scott Bakula (Captain Archer) recently had a long talk with fan and Astronaut
Mike Fincke on board the ISS. They would send DVDs of the show for him to
watch in orbit.

Fincke spoke of how the opening of the show helped him cope with the loss of
Columbia. Also the second starship on the show has been named after Shuttle
Columbia.
