Digital Media Broadcasting (DMB) is huge in Korea. It enables people to watch multimedia on their cellphones and these portable devices. People are watching TV on their cellphones all the time! Check out ESPN live here...from a student's phone! This picture was taken on the subway.
Most cabs are GPS enabled and they also subscribe to DMB...you might just be lucky enough to watch TV while you're in a cab...
Who needs a wireless headset for your cellphone, when you can just wedge it into your helmet?
There are taxi drivers in Seoul and then there are the REAL taxi drivers. Like this guy, with a Raid (a German racing parts company) steering wheel. This guy drove like he was starring in The Fast and the Furious--awesome!
