Allow me to me frank, during my 5-day trip there, Korea had nothing to surprise me, except two things.
One was its net speed. Every hotel, both large and small, provided 20 ~ 100+ mega bit per second high-speed broadband. Every where, you can just pick up your mobile phone and find numbers of stable, open and free wifi within seconds.
Another thing was a bit troublesome. Unless in Soul, which is the capital city, it’s really difficult to find someone who can speak English. After 5 minutes of explanation, the saleswoman still couldn’t get what I wanted to buy was just a piece of postcard. Moreover, the very few English words on the buildings and billboards did very little help to a lost man.
