After a couple of months waiting, finally here is the solution to the “Life Changes” mystery:
The Seoul Subway “DigitalView”.
It is all about some cabinets that have been installed at the the line 1, 2, 3, and 4 Seoul subway stations (what about the other lines?). These cabinets have an interactive map of the surroundings of the station, and a touch phone that allows paying phone calls using the T-money card.

I am not sure whether or not this will change anybody’s life, but I think it’s a great idea. These new booths have, on one side, a public telephone (during the testing period you can make free national calls, including cellphones!). On the other side there is room for an advertisement that I guess they will use to finance all the operation. In the center there is the main device, a huge touchscreen that very much reminds on an iPhone, showing information about the subway station’s emergency exits, nearby restaurants and interesting places, news, and even a Google Streetview-like interactive map of the subway station’s surroundings. They have called this map “Digital View”. I recorded a small video so that you can view the “device” in action:
