Seeing that there weren't much show-stopping problems with OS X Yosemite 10.10.0, I decided to proceed with updating my Mac mini server's OS from OS X Mavericks 10.9.5. Experiences with the Mountain Lion - Mavericks update helped in getting the web server back up running again relatively quickly. The downtime was only about 2 hours. Not much of a drama to write about.
One problem I noticed is that MySQL does not automatically start on reboot, and it seems to be a known problem. I'll have to remember to manually restart it when I have to reboot the server.
The nominal exchange rate is about KRW 1060 / US$ as of this writing, so the 6 Plus 128GB is about $1170 after taxes (or $1060 before). That's quite more expensive than the USA, where it's $949 before taxes. It turns out that Apple Korea is applying an exchange rate of KRW 1190 / US$, or KRW 130 (12.3%) more every dollar.
$649 x 1190 x 1.1 ~= KRW 849,500 (actual: 850,000)
$949 x 1190 x 1.1 ~= KRW 1,242,000 (actual: 1,240,000)
The baseline price that the mobile carriers have decided upon for selling the devices by themselves is only slightly cheaper by about KRW 30,000 50,000 to 60,000 (updated, see below). Yes, in Korea, even if you're entering a 2-year contract, the most expensive iPhone 6 Plus is more than twice as expensive as the US$499 that the people in the US is supposed to pay. Cheapest iPhone 6 should be about four times as expensive.
The applied exchange rate is about JPY 105 / US$, even though the nominal rate is higher at JPY 108 / US$. This means that Apple Japan is actually selling the iPhone 6 cheaper than compared to Apple USA.
$649 x 105 ~= JPY 68,100 (actual: 67,800)
$949 x 105 ~= JPY 99,600 (actual: 99,800)
JPY 99,800 x 9.98 ~= KRW 996,000
JPY 67,800 x 9.98 ~= KRW 676,000
That is considerably cheaper. Plus, the 8% sales tax is waived because of the tourist status, so the person doesn't pay more at the store. Once the person returns to Korea, the customs will impose the 10% VAT on the device for values exceeding US$600.
Given that low-cost airline fares for a round trip between Korea and Japan costs around KRW 200,000 or less, the person buying an iPhone 6 (Plus) in Japan will essentially be getting a free trip to Japan for the cost of buying one in Korea. The only major issue with this is that the device will not be eligible for official repairs or refurbishments within Korea.
So if you're a Korean who likes traveling and wants to buy an iPhone, and don't mind going to 3rd party repair shops, then reserve a phone at an Apple Store in Japan and book your flight to pick it up. All this thanks to the outrageous price-gouging by Apple Korea.
Update (16:30): I've taken a look at the prices for LGU+ (3rd largest mobile carrier in Korea) and this is how it goes:
It's slightly cheaper than what the iPhones traditionally cost from mobile carriers in Korea. It might be because this is the first time LGU+ is able to sell iPhones and it wanted a bit of price advantage.
It seems the carriers are trying to boost the total iPhone 6 sales overall by making the cheapest look cheaper. But the other models have increased in price to be just about KRW 50,000 less expensive than the Apple Store price across the board. But since the carriers will charge interest for the monthly installments during the contract period of two years, the total cost should be about the same in the end.
