Um, read the whole story. He's a lawyer and starting rounding up people for a class action law suit. There are 3 million iphone users in SK.
Do the math and apple could end up paying a billion (in US dollar).
I know I know, Apple has 70 billion in offshore accts etc.
There's a problem with your calculation. In a case about $946 you can bet that Apple didn't spend much on lawyers. This might even have been a small claims court with Apple not turning up at all. I think in the UK the limit for cases in small claims court is £3000, in Korea it might be one million won, so Apple might have chosen not even to defend itself.
In a class action lawsuit, things would look different.
