Tea! Earl Grey. Hot!

This short clips starts off with a comparison of Star Trek The Original Series gadgets (like the tricorder and Uhura's in-ear headset) and how they relate to modern-day technology (like 3D ultrasound and bluetooth handsfree headsets).
Personally there are still a lot of Star Trek technologies that I would still like to see implemented. The "beaming up" technology, of course, but also:

1. The replicator. Just shout "Tea. Earl Grey. Hot!" to this microwave style device and your cuppa tea materializes. And no dishwashing afterwards, either.
2. The sonic shower. Not sure what they do but I noticed that whoever uses it, steps out of the shower really happy and clean.
3. Holodecks. Just to able to practice the Klingon mating ritual without really killing anyone.
