One of the big problems, though, is getting reliable service for Apple products. Until recently, you had to journey to Seoul to use your Applecare warranty. However, Apple Service Centers are slowly moving southward and popping up in some other big cities.
If you live in Cheonan, where I'm based, the easiest store to reach is Neptune (also known as All-In-One-Tech), which is in the AK Plaza at Suwon Station. That is just about an hour from Cheonan via the subway. Follow the signs within the station complex to AK Plaza. Then keep taking the escalators upward to the 3rd or 4th floor - look for all the appliances and home-ware. Neptune is a very sleek glass-enclosed store.
I recently brought in my MacBook because the powercord port was damaged. The Neptune service technician, who might actually be the owner, took my mac apart and fixed the problem in about 10 minutes - no waiting in line. To top off the positive experience, he also speaks pretty fair English.
