The next stage for mainstream cell phones is higher communication speeds - broadband speeds, same as a cable modem. when that happens, we'll see lots of full motion live video posted on a website via cell phone (think 'cell phone cam').
at the same time, smaller packaging is always the goal of any technology...so it's easy to imagine full-motion real-time video streaming from someone's sunglasses - you see what they see, WHEN they are seeing it.
combine that with something like 'skype', and you have the Diick Tracy watches. we are already there. {ha, the censor blocked out 'D-i-c-k'}
every technology is used for good and bad. even the first telegraph system were used by criminals. The same telegraph that was being used to report them.
suicide bombers in Iraq have started streaming (at slow speeds and resolution) their own deaths which are posted on finatical websites as some kind of twisted recruitment and boasting tool. cell phones also are used as remote detonation devices.
of course, voice and video are not the only things that can be digitized and transmitted. technology is in use that already transmits vital signs from off-site patients, geological and atmospheric mesurements, and any other sensor you can think of.
The really weird ones are still in their infancy, but will eventually emerge in our lifetime. digitizing smell and taste, for instance, would be weird. imagine a restaurant transmiting the sample taste of their dishes in Italy to a tourist website. Or being able to smell the incense from inside a Buddhist temple in Kyoto from your living room.
It will be a long time before teleportation technology is available...but the way the technology heads now, slowly eliminates the need to actually be th..e..
