Internet and Computers
Internet in Korea has one of the highest rates of usage in the world. 
Brand name computers are not much cheaper in Korea than they are in the US and Canada. I can't comment on the UK or SA or NZ but they are a good deal cheaper than in Australia. If you're looking for a REAL deal, inexpensive clones can be picked up quite cheaply in the electronics market near Yongsan in Seoul.
It is very important to keep in mind that if you buy a computer in Korea it is going to come with a Korean operating system, and unless you are fluent in Korean, you are pretty much stuck if anything goes wrong and error messages start popping up in Korean. When buying the computer you can specifically ask that the English version of Windows be loaded on it.
If you choose to bring a computer from home make sure it can handle the power supply. Older computers will need a converter while newer computers have built in power converters. Virtually all laptops, unless you have a very ancient one, can accept 110-240. Check the power cord - the box/rectangular thingy should have a bunch of numbers on it. Look at the volts.
“I have been teaching in Keelung, Taiwan for over 1 year now, and plan to stay at least another. Footprints Recruiting was an invaluable service for me, assisting in many ways to ensure I had a smooth transition. Without their support, moving to Taiwan would have been much more difficult, and my experience much less enjoyable. I have, of course, become friends with other teachers, both in my school and elsewhere, who did not come via Footprints Recruiting. Many had encountered problems, such as teaching at an unprofessional school, visa problems, housing problems, etc. I am grateful I never had any such difficulties. My experience in Taiwan has been wonderful.”
