Very interesting - i actually registered just so I could respond to this.

I lived in Korea for two years, and was amazed at how fast everyone there could type. Little high school students would get on their cell phones (albeit a different setup than the keyboard) and they'd type faster on their cell phone than I could on a qwerty keyboard.
The Korean keyboard is set up so that all the vowels are one one side and the consonants on the other. The consonents are also divided up into types of consonents, but that would be tedious to decribe. Anyway, learning to type again was/is difficult, but not traumatizing; but it may be totally different learning to type in a different alphabet. Its even harder because I don't have a Korean keyboard at home, so I just have to fiddle around until i find the right key, sometimes.
Just thought you'd like to know....
